The introduction to a literature review serves as your reader’s guide through your academic work and thought process. Explore the significance of literature review introductions in review papers, academic papers, essays, theses, and dissertations. We delve into the purpose and necessity of these introductions, explore the essential components of literature review introductions, and provide step-by-step guidance on how to craft your own, along with examples.

Why you need an introduction for a literature review

When you need an introduction for a literature review, what to include in a literature review introduction, examples of literature review introductions, steps to write your own literature review introduction.

A literature review is a comprehensive examination of the international academic literature concerning a particular topic. It involves summarizing published works, theories, and concepts while also highlighting gaps and offering critical reflections.

In academic writing , the introduction for a literature review is an indispensable component. Effective academic writing requires proper paragraph structuring to guide your reader through your argumentation. This includes providing an introduction to your literature review.

It is imperative to remember that you should never start sharing your findings abruptly. Even if there isn’t a dedicated introduction section .

Instead, you should always offer some form of introduction to orient the reader and clarify what they can expect.

There are three main scenarios in which you need an introduction for a literature review:

  • Academic literature review papers: When your literature review constitutes the entirety of an academic review paper, a more substantial introduction is necessary. This introduction should resemble the standard introduction found in regular academic papers.
  • Literature review section in an academic paper or essay: While this section tends to be brief, it’s important to precede the detailed literature review with a few introductory sentences. This helps orient the reader before delving into the literature itself.
  • Literature review chapter or section in your thesis/dissertation: Every thesis and dissertation includes a literature review component, which also requires a concise introduction to set the stage for the subsequent review.

It is crucial to customize the content and depth of your literature review introduction according to the specific format of your academic work.

In practical terms, this implies, for instance, that the introduction in an academic literature review paper, especially one derived from a systematic literature review , is quite comprehensive. Particularly compared to the rather brief one or two introductory sentences that are often found at the beginning of a literature review section in a standard academic paper. The introduction to the literature review chapter in a thesis or dissertation again adheres to different standards.

Here’s a structured breakdown based on length and the necessary information:

Academic literature review paper

The introduction of an academic literature review paper, which does not rely on empirical data, often necessitates a more extensive introduction than the brief literature review introductions typically found in empirical papers. It should encompass:

  • The research problem: Clearly articulate the problem or question that your literature review aims to address.
  • The research gap: Highlight the existing gaps, limitations, or unresolved aspects within the current body of literature related to the research problem.
  • The research relevance: Explain why the chosen research problem and its subsequent investigation through a literature review are significant and relevant in your academic field.
  • The literature review method: If applicable, describe the methodology employed in your literature review, especially if it is a systematic review or follows a specific research framework.
  • The main findings or insights of the literature review: Summarize the key discoveries, insights, or trends that have emerged from your comprehensive review of the literature.
  • The main argument of the literature review: Conclude the introduction by outlining the primary argument or statement that your literature review will substantiate, linking it to the research problem and relevance you’ve established.
  • Preview of the literature review’s structure: Offer a glimpse into the organization of the literature review paper, acting as a guide for the reader. This overview outlines the subsequent sections of the paper and provides an understanding of what to anticipate.

By addressing these elements, your introduction will provide a clear and structured overview of what readers can expect in your literature review paper.

Regular literature review section in an academic article or essay

Most academic articles or essays incorporate regular literature review sections, often placed after the introduction. These sections serve to establish a scholarly basis for the research or discussion within the paper.

In a standard 8000-word journal article, the literature review section typically spans between 750 and 1250 words. The first few sentences or the first paragraph within this section often serve as an introduction. It should encompass:

  • An introduction to the topic: When delving into the academic literature on a specific topic, it’s important to provide a smooth transition that aids the reader in comprehending why certain aspects will be discussed within your literature review.
  • The core argument: While literature review sections primarily synthesize the work of other scholars, they should consistently connect to your central argument. This central argument serves as the crux of your message or the key takeaway you want your readers to retain. By positioning it at the outset of the literature review section and systematically substantiating it with evidence, you not only enhance reader comprehension but also elevate overall readability. This primary argument can typically be distilled into 1-2 succinct sentences.

In some cases, you might include:

  • Methodology: Details about the methodology used, but only if your literature review employed a specialized method. If your approach involved a broader overview without a systematic methodology, you can omit this section, thereby conserving word count.

By addressing these elements, your introduction will effectively integrate your literature review into the broader context of your academic paper or essay. This will, in turn, assist your reader in seamlessly following your overarching line of argumentation.

Introduction to a literature review chapter in thesis or dissertation

The literature review typically constitutes a distinct chapter within a thesis or dissertation. Often, it is Chapter 2 of a thesis or dissertation.

Some students choose to incorporate a brief introductory section at the beginning of each chapter, including the literature review chapter. Alternatively, others opt to seamlessly integrate the introduction into the initial sentences of the literature review itself. Both approaches are acceptable, provided that you incorporate the following elements:

  • Purpose of the literature review and its relevance to the thesis/dissertation research: Explain the broader objectives of the literature review within the context of your research and how it contributes to your thesis or dissertation. Essentially, you’re telling the reader why this literature review is important and how it fits into the larger scope of your academic work.
  • Primary argument: Succinctly communicate what you aim to prove, explain, or explore through the review of existing literature. This statement helps guide the reader’s understanding of the review’s purpose and what to expect from it.
  • Preview of the literature review’s content: Provide a brief overview of the topics or themes that your literature review will cover. It’s like a roadmap for the reader, outlining the main areas of focus within the review. This preview can help the reader anticipate the structure and organization of your literature review.
  • Methodology: If your literature review involved a specific research method, such as a systematic review or meta-analysis, you should briefly describe that methodology. However, this is not always necessary, especially if your literature review is more of a narrative synthesis without a distinct research method.

By addressing these elements, your introduction will empower your literature review to play a pivotal role in your thesis or dissertation research. It will accomplish this by integrating your research into the broader academic literature and providing a solid theoretical foundation for your work.

Comprehending the art of crafting your own literature review introduction becomes significantly more accessible when you have concrete examples to examine. Here, you will find several examples that meet, or in most cases, adhere to the criteria described earlier.

Example 1: An effective introduction for an academic literature review paper

To begin, let’s delve into the introduction of an academic literature review paper. We will examine the paper “How does culture influence innovation? A systematic literature review”, which was published in 2018 in the journal Management Decision.

introduction on a literature review

The entire introduction spans 611 words and is divided into five paragraphs. In this introduction, the authors accomplish the following:

  • In the first paragraph, the authors introduce the broader topic of the literature review, which focuses on innovation and its significance in the context of economic competition. They underscore the importance of this topic, highlighting its relevance for both researchers and policymakers.
  • In the second paragraph, the authors narrow down their focus to emphasize the specific role of culture in relation to innovation.
  • In the third paragraph, the authors identify research gaps, noting that existing studies are often fragmented and disconnected. They then emphasize the value of conducting a systematic literature review to enhance our understanding of the topic.
  • In the fourth paragraph, the authors introduce their specific objectives and explain how their insights can benefit other researchers and business practitioners.
  • In the fifth and final paragraph, the authors provide an overview of the paper’s organization and structure.

In summary, this introduction stands as a solid example. While the authors deviate from previewing their key findings (which is a common practice at least in the social sciences), they do effectively cover all the other previously mentioned points.

Example 2: An effective introduction to a literature review section in an academic paper

The second example represents a typical academic paper, encompassing not only a literature review section but also empirical data, a case study, and other elements. We will closely examine the introduction to the literature review section in the paper “The environmentalism of the subalterns: a case study of environmental activism in Eastern Kurdistan/Rojhelat”, which was published in 2021 in the journal Local Environment.

introduction on a literature review

The paper begins with a general introduction and then proceeds to the literature review, designated by the authors as their conceptual framework. Of particular interest is the first paragraph of this conceptual framework, comprising 142 words across five sentences:

“ A peripheral and marginalised nationality within a multinational though-Persian dominated Iranian society, the Kurdish people of Iranian Kurdistan (a region referred by the Kurds as Rojhelat/Eastern Kurdi-stan) have since the early twentieth century been subject to multifaceted and systematic discriminatory and exclusionary state policy in Iran. This condition has left a population of 12–15 million Kurds in Iran suffering from structural inequalities, disenfranchisement and deprivation. Mismanagement of Kurdistan’s natural resources and the degradation of its natural environmental are among examples of this disenfranchisement. As asserted by Julian Agyeman (2005), structural inequalities that sustain the domination of political and economic elites often simultaneously result in environmental degradation, injustice and discrimination against subaltern communities. This study argues that the environmental struggle in Eastern Kurdistan can be asserted as a (sub)element of the Kurdish liberation movement in Iran. Conceptually this research is inspired by and has been conducted through the lens of ‘subalternity’ ” ( Hassaniyan, 2021, p. 931 ).

In this first paragraph, the author is doing the following:

  • The author contextualises the research
  • The author links the research focus to the international literature on structural inequalities
  • The author clearly presents the argument of the research
  • The author clarifies how the research is inspired by and uses the concept of ‘subalternity’.

Thus, the author successfully introduces the literature review, from which point onward it dives into the main concept (‘subalternity’) of the research, and reviews the literature on socio-economic justice and environmental degradation.

While introductions to a literature review section aren’t always required to offer the same level of study context detail as demonstrated here, this introduction serves as a commendable model for orienting the reader within the literature review. It effectively underscores the literature review’s significance within the context of the study being conducted.

Examples 3-5: Effective introductions to literature review chapters

The introduction to a literature review chapter can vary in length, depending largely on the overall length of the literature review chapter itself. For example, a master’s thesis typically features a more concise literature review, thus necessitating a shorter introduction. In contrast, a Ph.D. thesis, with its more extensive literature review, often includes a more detailed introduction.

Numerous universities offer online repositories where you can access theses and dissertations from previous years, serving as valuable sources of reference. Many of these repositories, however, may require you to log in through your university account. Nevertheless, a few open-access repositories are accessible to anyone, such as the one by the University of Manchester . It’s important to note though that copyright restrictions apply to these resources, just as they would with published papers.

Master’s thesis literature review introduction

The first example is “Benchmarking Asymmetrical Heating Models of Spider Pulsar Companions” by P. Sun, a master’s thesis completed at the University of Manchester on January 9, 2024. The author, P. Sun, introduces the literature review chapter very briefly but effectively:

PhD thesis literature review chapter introduction

The second example is Deep Learning on Semi-Structured Data and its Applications to Video-Game AI, Woof, W. (Author). 31 Dec 2020, a PhD thesis completed at the University of Manchester . In Chapter 2, the author offers a comprehensive introduction to the topic in four paragraphs, with the final paragraph serving as an overview of the chapter’s structure:

PhD thesis literature review introduction

The last example is the doctoral thesis Metacognitive strategies and beliefs: Child correlates and early experiences Chan, K. Y. M. (Author). 31 Dec 2020 . The author clearly conducted a systematic literature review, commencing the review section with a discussion of the methodology and approach employed in locating and analyzing the selected records.

introduction on a literature review

Having absorbed all of this information, let’s recap the essential steps and offer a succinct guide on how to proceed with creating your literature review introduction:

  • Contextualize your review : Begin by clearly identifying the academic context in which your literature review resides and determining the necessary information to include.
  • Outline your structure : Develop a structured outline for your literature review, highlighting the essential information you plan to incorporate in your introduction.
  • Literature review process : Conduct a rigorous literature review, reviewing and analyzing relevant sources.
  • Summarize and abstract : After completing the review, synthesize the findings and abstract key insights, trends, and knowledge gaps from the literature.
  • Craft the introduction : Write your literature review introduction with meticulous attention to the seamless integration of your review into the larger context of your work. Ensure that your introduction effectively elucidates your rationale for the chosen review topics and the underlying reasons guiding your selection.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

  • Search for relevant literature
  • Evaluate sources
  • Identify themes, debates, and gaps
  • Outline the structure
  • Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

  • Quick Run-through
  • Step 1 & 2

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

  • Demonstrate your familiarity with the topic and its scholarly context
  • Develop a theoretical framework and methodology for your research
  • Position your work in relation to other researchers and theorists
  • Show how your research addresses a gap or contributes to a debate
  • Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

  • Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
  • Body image, self-perception, self-esteem, mental health
  • Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

  • Your university’s library catalogue
  • Google Scholar
  • Project Muse (humanities and social sciences)
  • Medline (life sciences and biomedicine)
  • EconLit (economics)
  • Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

  • What question or problem is the author addressing?
  • What are the key concepts and how are they defined?
  • What are the key theories, models, and methods?
  • Does the research use established frameworks or take an innovative approach?
  • What are the results and conclusions of the study?
  • How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
  • What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

You can use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

Receive feedback on language, structure, and formatting

Professional editors proofread and edit your paper by focusing on:

  • Academic style
  • Vague sentences
  • Style consistency

See an example

introduction on a literature review

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

  • Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
  • Themes: what questions or concepts recur across the literature?
  • Debates, conflicts and contradictions: where do sources disagree?
  • Pivotal publications: are there any influential theories or studies that changed the direction of the field?
  • Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

  • Most research has focused on young women.
  • There is an increasing interest in the visual aspects of social media.
  • But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

  • Look at what results have emerged in qualitative versus quantitative research
  • Discuss how the topic has been approached by empirical versus theoretical scholarship
  • Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

  • Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
  • Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
  • Critically evaluate: mention the strengths and weaknesses of your sources
  • Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

  • To familiarize yourself with the current state of knowledge on your topic
  • To ensure that you’re not just repeating what others have already done
  • To identify gaps in knowledge and unresolved problems that your research can address
  • To develop your theoretical framework and methodology
  • To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

  • An introductory paragraph that explains what your working topic and thesis is
  • A forecast of key topics or texts that will appear in the review
  • Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
  • Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
  • Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
  • Critically Evaluate: Mention the strengths and weaknesses of your sources
  • Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

  • Summarize the key findings you have taken from the literature and emphasize their significance
  • Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

  • Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
  • Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
  • Qualitative versus quantitative research
  • Empirical versus theoretical scholarship
  • Divide the research by sociological, historical, or cultural sources
  • Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

  • It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
  • Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
  • Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

What are Literature Reviews?

So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D.  The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.

Goals of Literature Reviews

What are the goals of creating a Literature Review?  A literature could be written to accomplish different aims:

  • To develop a theory or evaluate an existing theory
  • To summarize the historical or existing state of a research topic
  • Identify a problem in a field of research 

Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews .  Review of General Psychology , 1 (3), 311-320.

What kinds of sources require a Literature Review?

  • A research paper assigned in a course
  • A thesis or dissertation
  • A grant proposal
  • An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

Types of Literature Reviews

What kinds of literature reviews are written?

Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

  • Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework:  10.1177/08948453211037398  

Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.

  • Example : The effect of leave policies on increasing fertility: a systematic review:  10.1057/s41599-022-01270-w

Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.

  • Example : Employment Instability and Fertility in Europe: A Meta-Analysis:  10.1215/00703370-9164737

Meta-synthesis : "Qualitative meta-synthesis is a type of qualitative study that uses as data the findings from other qualitative studies linked by the same or related topic." (p.312). Zimmer, L. (2006). Qualitative meta-synthesis: A question of dialoguing with texts .  Journal of Advanced Nursing , 53 (3), 311-318.

  • Example : Women’s perspectives on career successes and barriers: A qualitative meta-synthesis:  10.1177/05390184221113735

What is a literature review?

A well-conducted literature review demonstrates the researcher’s familiarity with the existing literature, establishes the context for their own research, and contributes to scholarly conversations on the topic. One of the purposes of a literature review is also to help researchers avoid duplicating previous work and ensure that their research is informed by and builds upon the existing body of knowledge.

introduction on a literature review

What is the purpose of literature review?

A literature review serves several important purposes within academic and research contexts. Here are some key objectives and functions of a literature review: 2  

  • Contextualizing the Research Problem: The literature review provides a background and context for the research problem under investigation. It helps to situate the study within the existing body of knowledge. 
  • Identifying Gaps in Knowledge: By identifying gaps, contradictions, or areas requiring further research, the researcher can shape the research question and justify the significance of the study. This is crucial for ensuring that the new research contributes something novel to the field. 
  • Understanding Theoretical and Conceptual Frameworks: Literature reviews help researchers gain an understanding of the theoretical and conceptual frameworks used in previous studies. This aids in the development of a theoretical framework for the current research. 
  • Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered. 
  • Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research. 
  • Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature. 

Literature review example

Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic. 

Literature Review on Climate Change Impacts on Biodiversity:

Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies: 

a. Habitat Loss and Species Extinction:

Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements. 

b. Range Shifts and Phenological Changes:

Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources. 

c. Ocean Acidification and Coral Reefs:

The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems. 

d. Adaptive Strategies and Conservation Efforts:

Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning. 

introduction on a literature review

How to write a good literature review

Writing a literature review involves summarizing and synthesizing existing research on a particular topic. A good literature review format should include the following elements. 

Introduction: The introduction sets the stage for your literature review, providing context and introducing the main focus of your review. 

  • Opening Statement: Begin with a general statement about the broader topic and its significance in the field. 
  • Scope and Purpose: Clearly define the scope of your literature review. Explain the specific research question or objective you aim to address.

Conducting a literature review

Conducting a literature review is an essential step in research that involves reviewing and analyzing existing literature on a specific topic. It’s important to know how to do a literature review effectively, so here are the steps to follow: 1  

Choose a Topic and Define the Research Question:

  • Select a topic that is relevant to your field of study. 
  • Clearly define your research question or objective. Determine what specific aspect of the topic do you want to explore? 

Decide on the Scope of Your Review:

  • Determine the timeframe for your literature review. Are you focusing on recent developments, or do you want a historical overview? 
  • Consider the geographical scope. Is your review global, or are you focusing on a specific region? 
  • Define the inclusion and exclusion criteria. What types of sources will you include? Are there specific types of studies or publications you will exclude? 

Select Databases for Searches:

  • Identify relevant databases for your field. Examples include PubMed, IEEE Xplore, Scopus, Web of Science, and Google Scholar. 
  • Consider searching in library catalogs, institutional repositories, and specialized databases related to your topic. 

Conduct Searches and Keep Track:

  • Develop a systematic search strategy using keywords, Boolean operators (AND, OR, NOT), and other search techniques. 
  • Record and document your search strategy for transparency and replicability. 
  • Keep track of the articles, including publication details, abstracts, and links. Use citation management tools like EndNote, Zotero, or Mendeley to organize your references. 

Review the Literature:

  • Evaluate the relevance and quality of each source. Consider the methodology, sample size, and results of studies. 
  • Organize the literature by themes or key concepts. Identify patterns, trends, and gaps in the existing research. 
  • Summarize key findings and arguments from each source. Compare and contrast different perspectives. 
  • Identify areas where there is a consensus in the literature and where there are conflicting opinions. 
  • Provide critical analysis and synthesis of the literature. What are the strengths and weaknesses of existing research? 

Organize and Write Your Literature Review:

  • Literature review outline should be based on themes, chronological order, or methodological approaches. 
  • Write a clear and coherent narrative that synthesizes the information gathered. 
  • Use proper citations for each source and ensure consistency in your citation style (APA, MLA, Chicago, etc.). 
  • Conclude your literature review by summarizing key findings, identifying gaps, and suggesting areas for future research. 

The literature review sample and detailed advice on writing and conducting a review will help you produce a well-structured report. But remember that a literature review is an ongoing process, and it may be necessary to revisit and update it as your research progresses. 

Frequently asked questions

A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.

Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.  

Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic. 

Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods. 

Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers.  Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved.  Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic.  Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings.  Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject.  It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.

The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review:  Introduction:   Provide an overview of the topic.  Define the scope and purpose of the literature review.  State the research question or objective.  Body:   Organize the literature by themes, concepts, or chronology.  Critically analyze and evaluate each source.  Discuss the strengths and weaknesses of the studies.  Highlight any methodological limitations or biases.  Identify patterns, connections, or contradictions in the existing research.  Conclusion:   Summarize the key points discussed in the literature review.  Highlight the research gap.  Address the research question or objective stated in the introduction.  Highlight the contributions of the review and suggest directions for future research.

Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research.

There are five key steps to writing a literature review:

  • Search for relevant literature
  • Evaluate sources
  • Identify themes, debates and gaps
  • Outline the structure
  • Write your literature review

A good literature review doesn’t just summarise sources – it analyses, synthesises, and critically evaluates to give a clear picture of the state of knowledge on the subject.

  • Quick Run-through
  • Step 1 & 2

When you write a dissertation or thesis, you will have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

  • Demonstrate your familiarity with the topic and scholarly context
  • Develop a theoretical framework and methodology for your research
  • Position yourself in relation to other researchers and theorists
  • Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. We’ve written a step-by-step guide that you can follow below.

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

  • Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
  • Body image, self-perception, self-esteem, mental health
  • Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

  • Your university’s library catalogue
  • Google Scholar
  • Project Muse (humanities and social sciences)
  • Medline (life sciences and biomedicine)
  • EconLit (economics)
  • Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

  • What question or problem is the author addressing?
  • What are the key concepts and how are they defined?
  • What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
  • What are the results and conclusions of the study?
  • How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
  • How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
  • What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

You can use our free APA Reference Generator for quick, correct, consistent citations.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

  • Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
  • Themes: what questions or concepts recur across the literature?
  • Debates, conflicts and contradictions: where do sources disagree?
  • Pivotal publications: are there any influential theories or studies that changed the direction of the field?
  • Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

  • Most research has focused on young women.
  • There is an increasing interest in the visual aspects of social media.
  • But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

  • Look at what results have emerged in qualitative versus quantitative research
  • Discuss how the topic has been approached by empirical versus theoretical scholarship
  • Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

  • Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
  • Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
  • Critically evaluate: mention the strengths and weaknesses of your sources.
  • Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

  • To familiarise yourself with the current state of knowledge on your topic
  • To ensure that you’re not just repeating what others have already done
  • To identify gaps in knowledge and unresolved problems that your research can address
  • To develop your theoretical framework and methodology
  • To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

A literature review surveys, summarizes, critically analyzes, compares, and synthesizes multiple scholarly works, or published knowledge on a particular topic or specific subject area.

Literature can include peer-reviewed or scholarly  articles, books/ ebooks, conference proceedings, theses/ dissertations, documents published by governmental agencies and non-profit organizations, and other forms of gray literature.

Conducting a literature review is part of the research process and serves to establish a base of knowledge and overview of the principal works on a specific area of research as well as identify important themes, discoveries, areas of consensus and debate, changes over time, and provide a foundation for further research.

A literature review may be written to:

  •     Synthesize past and current literature on a topic
  •     Identify a problem in a field of research  
  •     Show how the literature relates to one another
  •     Place your work in the the context of other related research

What kinds of sources require a Literature Review?

  •     A thesis or dissertation
  •     A grant proposal
  •     A research paper assigned in a course 
  •     An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

The following are common types of literature reviews:

Narrative or Traditional Review

The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

Systematic Review

The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find.

Meta-analysis

This type of review utilizes quantitative methods to combine the results of independent studies and synthesize summaries and conclusions which can be used to evaluate therapeutic effectiveness, plan new studies, etc.

Meta-synthesis

A meta-synthesis is a type of qualitative study that uses as data the findings from other qualitative studies linked by the same or related topic.

The Most Important Thing

The best time to write an introduction is AFTER you write the body of your paper.

Well, how do you know what to introduce until after you've figured out what you want to say?

The best time to write an introduction is as one of the last things you do.

Basic Introduction Template

For any other sort of scholarly writing, the following basic structure works well for an introduction:

  • What has been said or done on this topic?  
  • What is the problem with what has been said or done?
  • What will you offer to solve the problem?  (The answer to this is your thesis statement.)
  • How does your solution address necessary change?

Writing an Introduction

The job of an introduction is to preview what you are going to say so the audience knows what is coming.  A good introduction starts out generally and works towards a specific statement of what you intend to discuss in your writing. 

The introduction explains the focus and establishes the importance of the subject. It discusses what kind of work has been done on the topic and identifies any controversies within the field or any recent research which has raised questions about earlier assumptions. It may provide background or history, and it indicates why the topic is important, interesting, problematic, or relevant in some way.  It concludes with a purpose or thesis statement. In a stand-alone literature review, this statement will sum up and evaluate the state of the art in this field of research; in a review that is an introduction or preparatory to a larger work, such as the Culminating Project, it will suggest how the review findings will lead to the research the writer proposes to undertake.

In a literature review, an introduction may contain the following:

  • A concise definition of a topic under consideration (this may be a descriptive or argumentative thesis, or proposal), as well as the scope of the related literature being investigated. (Example: If the topic under consideration is ‘women’s wartime diaries’, the scope of the review may be limited to published or unpublished works, works in English, works from a particular location, time period, or conflict, etc.)  
  • The introduction should also note what topics are being included and what are intentional exclusions. (Example: “This review will not explore the diaries of adolescent girls.”)
  • A final sentence should signal the list of key topics that will be used to discuss the selected sources.

Many theories have been proposed to explain what motivates human behavior. Although the literature covers a wide variety of such theories, this review will focus on five major themes which emerge repeatedly throughout the literature reviewed. These themes are incorporation of the self-concept into traditional theories of motivation, the influence of rewards on motivation, the increasing importance of internal forces of motivation, autonomy and self-control as sources of motivation, and narcissism as an essential component of motivation. Although the literature presents these themes in a variety of contexts, this paper will primarily focus on their application to self-motivation.

Let's break that apart.

How To Write An A-Grade Literature Review

3 straightforward steps (with examples) + free template.

By: Derek Jansen (MBA) | Expert Reviewed By: Dr. Eunice Rautenbach | October 2019

Quality research is about building onto the existing work of others , “standing on the shoulders of giants”, as Newton put it. The literature review chapter of your dissertation, thesis or research project is where you synthesise this prior work and lay the theoretical foundation for your own research.

Long story short, this chapter is a pretty big deal, which is why you want to make sure you get it right . In this post, I’ll show you exactly how to write a literature review in three straightforward steps, so you can conquer this vital chapter (the smart way).

Overview: The Literature Review Process

  • Understanding the “ why “
  • Finding the relevant literature
  • Cataloguing and synthesising the information
  • Outlining & writing up your literature review
  • Example of a literature review

But first, the “why”…

Before we unpack how to write the literature review chapter, we’ve got to look at the why . To put it bluntly, if you don’t understand the function and purpose of the literature review process, there’s no way you can pull it off well. So, what exactly is the purpose of the literature review?

Well, there are (at least) four core functions:

  • For you to gain an understanding (and demonstrate this understanding) of where the research is at currently, what the key arguments and disagreements are.
  • For you to identify the gap(s) in the literature and then use this as justification for your own research topic.
  • To help you build a conceptual framework for empirical testing (if applicable to your research topic).
  • To inform your methodological choices and help you source tried and tested questionnaires (for interviews ) and measurement instruments (for surveys ).

Most students understand the first point but don’t give any thought to the rest. To get the most from the literature review process, you must keep all four points front of mind as you review the literature (more on this shortly), or you’ll land up with a wonky foundation.

Okay – with the why out the way, let’s move on to the how . As mentioned above, writing your literature review is a process, which I’ll break down into three steps:

  • Finding the most suitable literature
  • Understanding , distilling and organising the literature
  • Planning and writing up your literature review chapter

Importantly, you must complete steps one and two before you start writing up your chapter. I know it’s very tempting, but don’t try to kill two birds with one stone and write as you read. You’ll invariably end up wasting huge amounts of time re-writing and re-shaping, or you’ll just land up with a disjointed, hard-to-digest mess . Instead, you need to read first and distil the information, then plan and execute the writing.

Free Webinar: Literature Review 101

Step 1: Find the relevant literature

Naturally, the first step in the literature review journey is to hunt down the existing research that’s relevant to your topic. While you probably already have a decent base of this from your research proposal , you need to expand on this substantially in the dissertation or thesis itself.

Essentially, you need to be looking for any existing literature that potentially helps you answer your research question (or develop it, if that’s not yet pinned down). There are numerous ways to find relevant literature, but I’ll cover my top four tactics here. I’d suggest combining all four methods to ensure that nothing slips past you:

Method 1 – Google Scholar Scrubbing

Google’s academic search engine, Google Scholar , is a great starting point as it provides a good high-level view of the relevant journal articles for whatever keyword you throw at it. Most valuably, it tells you how many times each article has been cited, which gives you an idea of how credible (or at least, popular) it is. Some articles will be free to access, while others will require an account, which brings us to the next method.

Method 2 – University Database Scrounging

Generally, universities provide students with access to an online library, which provides access to many (but not all) of the major journals.

So, if you find an article using Google Scholar that requires paid access (which is quite likely), search for that article in your university’s database – if it’s listed there, you’ll have access. Note that, generally, the search engine capabilities of these databases are poor, so make sure you search for the exact article name, or you might not find it.

Method 3 – Journal Article Snowballing

At the end of every academic journal article, you’ll find a list of references. As with any academic writing, these references are the building blocks of the article, so if the article is relevant to your topic, there’s a good chance a portion of the referenced works will be too. Do a quick scan of the titles and see what seems relevant, then search for the relevant ones in your university’s database.

Method 4 – Dissertation Scavenging

Similar to Method 3 above, you can leverage other students’ dissertations. All you have to do is skim through literature review chapters of existing dissertations related to your topic and you’ll find a gold mine of potential literature. Usually, your university will provide you with access to previous students’ dissertations, but you can also find a much larger selection in the following databases:

  • Open Access Theses & Dissertations
  • Stanford SearchWorks

Keep in mind that dissertations and theses are not as academically sound as published, peer-reviewed journal articles (because they’re written by students, not professionals), so be sure to check the credibility of any sources you find using this method. You can do this by assessing the citation count of any given article in Google Scholar. If you need help with assessing the credibility of any article, or with finding relevant research in general, you can chat with one of our Research Specialists .

Alright – with a good base of literature firmly under your belt, it’s time to move onto the next step.

Step 2: Log, catalogue and synthesise

Once you’ve built a little treasure trove of articles, it’s time to get reading and start digesting the information – what does it all mean?

While I present steps one and two (hunting and digesting) as sequential, in reality, it’s more of a back-and-forth tango – you’ll read a little , then have an idea, spot a new citation, or a new potential variable, and then go back to searching for articles. This is perfectly natural – through the reading process, your thoughts will develop , new avenues might crop up, and directional adjustments might arise. This is, after all, one of the main purposes of the literature review process (i.e. to familiarise yourself with the current state of research in your field).

As you’re working through your treasure chest, it’s essential that you simultaneously start organising the information. There are three aspects to this:

  • Logging reference information
  • Building an organised catalogue
  • Distilling and synthesising the information

I’ll discuss each of these below:

2.1 – Log the reference information

As you read each article, you should add it to your reference management software. I usually recommend Mendeley for this purpose (see the Mendeley 101 video below), but you can use whichever software you’re comfortable with. Most importantly, make sure you load EVERY article you read into your reference manager, even if it doesn’t seem very relevant at the time.

2.2 – Build an organised catalogue

In the beginning, you might feel confident that you can remember who said what, where, and what their main arguments were. Trust me, you won’t. If you do a thorough review of the relevant literature (as you must!), you’re going to read many, many articles, and it’s simply impossible to remember who said what, when, and in what context . Also, without the bird’s eye view that a catalogue provides, you’ll miss connections between various articles, and have no view of how the research developed over time. Simply put, it’s essential to build your own catalogue of the literature.

I would suggest using Excel to build your catalogue, as it allows you to run filters, colour code and sort – all very useful when your list grows large (which it will). How you lay your spreadsheet out is up to you, but I’d suggest you have the following columns (at minimum):

  • Author, date, title – Start with three columns containing this core information. This will make it easy for you to search for titles with certain words, order research by date, or group by author.
  • Categories or keywords – You can either create multiple columns, one for each category/theme and then tick the relevant categories, or you can have one column with keywords.
  • Key arguments/points – Use this column to succinctly convey the essence of the article, the key arguments and implications thereof for your research.
  • Context – Note the socioeconomic context in which the research was undertaken. For example, US-based, respondents aged 25-35, lower- income, etc. This will be useful for making an argument about gaps in the research.
  • Methodology – Note which methodology was used and why. Also, note any issues you feel arise due to the methodology. Again, you can use this to make an argument about gaps in the research.
  • Quotations – Note down any quoteworthy lines you feel might be useful later.
  • Notes – Make notes about anything not already covered. For example, linkages to or disagreements with other theories, questions raised but unanswered, shortcomings or limitations, and so forth.

If you’d like, you can try out our free catalog template here (see screenshot below).

Excel literature review template

2.3 – Digest and synthesise

Most importantly, as you work through the literature and build your catalogue, you need to synthesise all the information in your own mind – how does it all fit together? Look for links between the various articles and try to develop a bigger picture view of the state of the research. Some important questions to ask yourself are:

  • What answers does the existing research provide to my own research questions ?
  • Which points do the researchers agree (and disagree) on?
  • How has the research developed over time?
  • Where do the gaps in the current research lie?

To help you develop a big-picture view and synthesise all the information, you might find mind mapping software such as Freemind useful. Alternatively, if you’re a fan of physical note-taking, investing in a large whiteboard might work for you.

Mind mapping is a useful way to plan your literature review.

Step 3: Outline and write it up!

Once you’re satisfied that you have digested and distilled all the relevant literature in your mind, it’s time to put pen to paper (or rather, fingers to keyboard). There are two steps here – outlining and writing:

3.1 – Draw up your outline

Having spent so much time reading, it might be tempting to just start writing up without a clear structure in mind. However, it’s critically important to decide on your structure and develop a detailed outline before you write anything. Your literature review chapter needs to present a clear, logical and an easy to follow narrative – and that requires some planning. Don’t try to wing it!

Naturally, you won’t always follow the plan to the letter, but without a detailed outline, you’re more than likely going to end up with a disjointed pile of waffle , and then you’re going to spend a far greater amount of time re-writing, hacking and patching. The adage, “measure twice, cut once” is very suitable here.

In terms of structure, the first decision you’ll have to make is whether you’ll lay out your review thematically (into themes) or chronologically (by date/period). The right choice depends on your topic, research objectives and research questions, which we discuss in this article .

Once that’s decided, you need to draw up an outline of your entire chapter in bullet point format. Try to get as detailed as possible, so that you know exactly what you’ll cover where, how each section will connect to the next, and how your entire argument will develop throughout the chapter. Also, at this stage, it’s a good idea to allocate rough word count limits for each section, so that you can identify word count problems before you’ve spent weeks or months writing!

PS – check out our free literature review chapter template…

3.2 – Get writing

With a detailed outline at your side, it’s time to start writing up (finally!). At this stage, it’s common to feel a bit of writer’s block and find yourself procrastinating under the pressure of finally having to put something on paper. To help with this, remember that the objective of the first draft is not perfection – it’s simply to get your thoughts out of your head and onto paper, after which you can refine them. The structure might change a little, the word count allocations might shift and shuffle, and you might add or remove a section – that’s all okay. Don’t worry about all this on your first draft – just get your thoughts down on paper.

start writing

Once you’ve got a full first draft (however rough it may be), step away from it for a day or two (longer if you can) and then come back at it with fresh eyes. Pay particular attention to the flow and narrative – does it fall fit together and flow from one section to another smoothly? Now’s the time to try to improve the linkage from each section to the next, tighten up the writing to be more concise, trim down word count and sand it down into a more digestible read.

Once you’ve done that, give your writing to a friend or colleague who is not a subject matter expert and ask them if they understand the overall discussion. The best way to assess this is to ask them to explain the chapter back to you. This technique will give you a strong indication of which points were clearly communicated and which weren’t. If you’re working with Grad Coach, this is a good time to have your Research Specialist review your chapter.

Finally, tighten it up and send it off to your supervisor for comment. Some might argue that you should be sending your work to your supervisor sooner than this (indeed your university might formally require this), but in my experience, supervisors are extremely short on time (and often patience), so, the more refined your chapter is, the less time they’ll waste on addressing basic issues (which you know about already) and the more time they’ll spend on valuable feedback that will increase your mark-earning potential.

Let’s Recap

In this post, we’ve covered how to research and write up a high-quality literature review chapter. Let’s do a quick recap of the key takeaways:

  • It is essential to understand the WHY of the literature review before you read or write anything. Make sure you understand the 4 core functions of the process.
  • The first step is to hunt down the relevant literature . You can do this using Google Scholar, your university database, the snowballing technique and by reviewing other dissertations and theses.
  • Next, you need to log all the articles in your reference manager , build your own catalogue of literature and synthesise all the research.
  • Following that, you need to develop a detailed outline of your entire chapter – the more detail the better. Don’t start writing without a clear outline (on paper, not in your head!)
  • Write up your first draft in rough form – don’t aim for perfection. Remember, done beats perfect.
  • Refine your second draft and get a layman’s perspective on it . Then tighten it up and submit it to your supervisor.

The Literature Review (LR) is an integral part of an in-depth research process, which involves critically scrutinized content attained from former research works and empirical reports. In a research paper , the LR is meant to address the identified issue and gain adequate knowledge to resolve it. However, since every research is unique in its way, soon the researcher discovers that the former research works are inadequate or limited in meeting the current research objectives. In this way, the LR brings forth the research gaps, which leads to further research process at the researcher’s end. 

It is important to note here that the Literature Review format may differ from one University to another. However, the process of analysis and declarations remain universal. For the formatting and the inclusion list always check the University module.

In this article, we will focus on understanding the relevance and content to be established in the Introduction part of the Literature Review.

On a standard basis, the structure of the Literature Review is meant to offer three sections – Introduction, Body, and the Conclusion. In the case of Introduction, the researcher must offer detailed information about the context and the intellectual narration about the topic. Historical contexts and the developmental process of the concern need to be summed up in this section. The researcher should declare the theories and the relevance of the theories to the research in a very comprehensive manner. While elaborating the relevance of the selected theories the key writers and philosophers should be introduced in the Introduction section of the LR. 

Sample Text 1 - Literature Review Introduction Sample

It is highly recommended that the researcher considers the inclusion of the Conceptual Framework in the LR Introduction. The objective behind the inclusion of the Conceptual Framework is to develop an in-depth thinking process and thereby understand the complexity of the identified issue of the research. This framework acts as a roadmap while constructing the Body and Conclusion or the Research Gaps. The conceptual framework as prescribed in Figure 1 should be considered while answering the specified questions one-by-one:

Figure 1: Map to Construct the Conceptual Framework

Map to Construct the Conceptual Framework - Literature Review Introduction Sample - Words Doctorate

The Literature Review Introduction can vary as per the type of review process considered by the researcher. Following the selected topic and the availability of secondary sources the LR can be:

  • A narrative or argumentative type,
  • A systematic review type with either of meta-synthesis or meta-analysis approach, or
  • A theoretical or integrative review type.

For all these types, it is necessary that the Literature Review Introduction makes clear declarations about the selection process and justify the selection of the type in the most intellectually logical manner.

If you select the narrative approach to review the collected literature, then mention it in the first few lines. You need to state that you will summarise the content of the selected literature and will derive the research gaps.

Alternatively, your literature review can be argumentative in approach. In this case, the Literature Review Introduction must declare the process of examining the biases and ways to identify the shortcomings of the selected literature.

In case, you select a systematic review of very narrowly selected literature; make sure that you identify the right process. Since systematic literature review can be shaped as meta-analysis or as meta-synthesis, the LR Introduction must clarify the approach. Mention how you follow statistical procedures to meet the meta-analysis approach and undergo a deductive process under quantitative methodology. For the meta-synthesis approach, give a clear idea about the non-statistical techniques under qualitative methodology.

For the theoretical approach of the literature review, introduce and establish the relevance of the selected theories in the LR Introduction. On the other hand, for the integrative review approach, generate the necessary framework about the process of leading the critiques.

Sample Text 2 - Literature Review Introduction Sample

The literature Review Introduction will not mention anything about the selected referencing style. The in-text citations will make it all clear. You must follow the right kind of in-text referencing style as per your selected subject and approach of your research.

In this article, we are offering three samples for a clear understanding. These exemplified referencing styles are:

  • American Psychological Association (APA) referencing system,
  • Chicago referencing or Chicago Manual of Style (CMOS), &
  • Modern Languages Association (MLA) referencing system.

It is the presence of the references in the form of ‘parenthetical in-text citations, which determines the selected referencing style for the entire research work. Note that for subjects from Humanities, the common selection is of MLA style. Even in Humanities, if you are from dealing with History, Business Fine Arts, then you can consider the Chicago style of referencing. As for the APA referencing style the subjects from Social Sciences, Engineering, Education, etc. remains as the basic selection.  Still, we would recommend that always have a consultation with your Guide or Supervisor about the right selection of the referencing style.

APA Style (7 th edition)

APA style  of referencing under 7 th edition is a parenthetical way of declaring the references. The bracketed mode of references that you need to add to the Literature Review Introduction must comprise of –

  • The Surname of the Author
  • Publication Date

For instance, in Sample Text 1 for a fictitious book, ‘Evaluation of Education System’ by Simon Hillary , published in 2019; the APA style in-text referencing should appear like- (Hillary, 2019, p. 84) or (Hillary, 2019, pp. 84-88). Note that ‘p.’ stands for a single page, whereas ‘pp.’ for consecutive multiple pages. The page or page numbers are used when you quote from a text directly. In case there is no direct quote, you can avoid using the page or page numbers. In some cases like old texts, it is recommended to use paragraph or couplet numbers.

This format is a general application that varies slightly in the case of multiple authors. Let’s add Walter as co-author for two authored books. The in-text citations under the APA system follow the following provisions of using the commas ‘,’: There is no difference while referring to in-text reference to any book, journal or web article, or internet sources.

  • For a book with a single author: (Hillary, 2019, p. 84) or (Hillary, 2019, pp. 84-88)
  • For a book with two authors: (Hillary and Walter, 2019, p. 84) or (Hillary and Walter, 2019, pp. 84-88)
  • For a book with multiple authors: (Hillary et al., 2019, p. 84) or (Hillary et al., 2019, pp. 84-88)
  • Journal Article (both Print & Electronic), single author: (Hillary, 2019, p. 84) or (Hillary, 2019, pp. 84-88)
  • Journal Article (both Print & Electronic), two authors: (Hillary and Walter, 2019, p. 84) or (Hillary and Walter, 2019, pp. 84-88)
  • Journal Article (both Print & Electronic), multiple authors: (Hillary et al., 2019, p. 84) or (Hillary et al., 2019, pp. 84-88)
  • Web Articles or Internet Sources, single author: (Hillary, 2019, p. 84) or (Hillary, 2019, pp. 84-88)
  • Web Articles or Internet Sources, two authors: (Hillary and Walter, 2019, p. 84) or (Hillary and Walter, 2019, pp. 84-88)
  • Web Articles or Internet Sources, multiple authors: (Hillary et al., 2019, p. 84) or (Hillary et al., 2019, pp. 84-88)

For APA in-text citations always remember:

  • To capitalise all the proper nouns, this will include the surname/s of the author or authors,
  • To capitalise the first alphabet of every word of any title is included in the text. Here, the prepositions and articles can remain in small letters.
  • Indent of ½ inch from left for every direct quote in the text.

Chicago Style (17 th edition)

Chicago referencing style (17 th edition) is used for documentations of –

  • Author-date citations, &
  • Notes and bibliography.

Though this style is very similar to the APA style of adding-

Yet the placement of the comma makes all the difference in the in-text citation process. Instead of putting the comma ‘,’ after the Surname of the Author, Chicago places it after the publication date and there is no space for ‘p.’ or ‘pp.’.

If we consider the same text ‘Evaluation of Education System’ by Simon Hillary, published in 2019 by Oxford Open Press in Oxford; the Chicago style in-text referencing should appear like- (Hillary 2019, 84) or (Hillary 2019, 84-88). Let’s add Walter as co-author for two authored books.

Author-date (in-text)

There is no difference while referring to in-text reference to any book, journal or web article, or internet sources.

  • For a book with a single author: (Hillary 2019, 84) or (Hillary 2019, 84-88)
  • For a book with two authors: (Hillary and Walter 2019, 84) or (Hillary and Walter 2019, 84-88)
  • For a book with multiple authors: (Hillary et al 2019, 84) or (Hillary et al 2019, 84-88)
  • Journal Article (both Print & Electronic), single author: (Hillary 2019, 84) or (Hillary 2019, 84-88)
  • Journal Article (both Print & Electronic), two authors: (Hillary and Walter 2019, 84) or (Hillary and Walter 2019, 84-88)
  • Journal Article (both Print & Electronic), multiple authors: (Hillary et al 2019, 84) or (Hillary et al 2019, 84-88)
  • Web Articles or Internet Sources, single author: (Hillary 2019, 84) or (Hillary 2019, 84-88)
  • Web Articles or Internet Sources, two authors: (Hillary and Walter 2019, 84) or (Hillary and Walter 2019, 84-88)
  • Web Articles or Internet Sources, multiple authors: (Hillary et al 2019, 84) or (Hillary et al 2019, 84-88)

The usage of Chicago is more particular when it comes to the inclusion of footnote or endnote in a text. Here, if you need to add any footnote or endnote to the Literature Review Introduction, then follow the following rules:

  • For book: Full name of the Author, Book title (Place of Publication: Publisher, Publication year) page number/s
  • Simon Hillary, Evaluation of Education System (Oxford: Oxford Open Press, 2019), 84-88
  • Following in-text mentions – Hillary, Evaluation of Education System, 84-88
  • For Journal Article: Full name of the Author, “Article Title,” Journal Name, Journal Volume, Journal No., Journal Issue (Month, Year): page number/s. Add DOI for electronic Journal publication.
  • Edmund Walter, “Education System and Global Policies.” Journal for Intellect, 26, no. 3 (Summer, 2019): 65. https://doi.org/16.2329/jfiunivbchro.26.3.0065.
  • Following in-text mentions – Walter, “Education System and Global Policies,” 65.
  • For Web Articles or Internet Sources- “Page Title,” Name of the Website, Date of Access (Month-date-year), URL.
  • “About Education System,” Educationresearch, accessed July 13, 2021, http://www.wr.dn/en/about-referencing-style.
  • Following in-text mentions – “About Education System.”

Sample Text 4 - Literature Review Introduction Sample

MLA Style (8 th edition)

MLA referencing style under 8 th edition is also a parenthetical way of declaring the references. The brackets in the in-text referencing process for the Introduction of your Literature Review must comprise of –

  • The Surname of the Author, and
  • Page number/s of the text or context.

Considering the same book, ‘Evaluation of Education System’ by Simon Hillary, published in 2019; the MLA style in-text referencing should appear like- (Hillary 84) or (Hillary 84-88). It is important that in the case of MLA the non-consecutive pages are just added by commas, as in- (Hillary 84, 26, 104). Let’s add Walter as co-author for two authored books. There is no difference while referring to in-text reference to any book, journal or web article, or internet sources. Note that there is no use of ‘p.’ or ‘pp.’ for page number/s and there is no space for commas ‘,’.

  • For a book with a single author: (Hillary 84) or (Hillary 84-88)
  • For a book with two authors: (Hillary and Walter 84) or (Hillary and Walter 84-88)
  • For a book with multiple authors: (Hillary et al 84) or (Hillary et al 84-88)
  • Journal Article (both Print & Electronic), single author: (Hillary 84) or (Hillary 84-88)
  • Journal Article (both Print & Electronic), two authors: (Hillary and Walter 84) or (Hillary and Walter 84-88)
  • Journal Article (both Print & Electronic), multiple authors: (Hillary et al 84) or (Hillary et al 84-88)
  • Web Articles or Internet Sources, single author: (Hillary 84) or (Hillary 84-88)
  • Web Articles or Internet Sources, two authors: (Hillary and Walter 84) or (Hillary and Walter 84-88)
  • Web Articles or Internet Sources, multiple authors: (Hillary et al 84) or (Hillary et al 84-88)

The MLA style is popular for its facilities to accommodate various kinds of exceptional in-text citations. In your Literature Review Introduction, these exceptions can occur in the following manner, yet MLA holds solutions for the-

No Author Citation: The in-text citation needs to be added by matching the very foremost element in the entry of the Cited Work, which can be the organisation’s name or source title.

Example: For the source- United Nations International Children's Emergency Fund. International Annual Report for FY 2020-21, the in-text citation would be UNICEF (or United Nations International Children's Emergency Fund) 162.

No Page Number/s Citation: In an in-text citation, when there is no page number, then you can consider the number of the chapter, scene, section, or anything that can locate the page.

Example: For the source- ‘Evaluation of Education System’ by Simon Hillary, the in-text citation would be (Hillary ch 2).

Same Author Different Sources:   The in-text citation of different works by the same author, MLA follows the regulation of shortening the title of the sources.

Example: For the source- ‘Evaluation of Education System’ by Simon Hillary, and ‘Education in Global Platform’ by Simon Hillary, the in-text citation would be (Hillary, Evaluation 84; and Hilary, Global 65).

Same Last Names: The in-text citation of different authors with the same surnames, MLA follows the trend of adding the First name initial.

Example: For the authors- Thomas Hilary and Simon Hilary with different sources, the in-text citation would be (T. Hillary 65 & S. Hillary 84).

Indirect Citation: The in-text citation for the information attained from indirect sources, MLA prescribes the provision of adding the source with parentheses and by the end of the sentence.

Example: If a piece of information about Hillary has been gathered from James Walter’s text published in 2020, then the in-text citation would be Hillary declared that the style of referencing … (Walter ch.2)

MLA style is very peculiar for its art of paraphrasing or delivering the context with the sources. For instance, in your Introduction, you can have sentences like-

Sample Text 5 - Literature Review Introduction Sample - Words Doctorate

In the conclusion, it is suggested that the Literature Review Introduction is very important for the success of your research However, to get your research approved by the University you need to take care of all the aspects and points mentioned above.

The type of literature review you do will depend on a variety of factors:

  • Your discipline
  • The purpose - undergraduate assessment, PHD thesis, journal article?
  • Your lecturer or supervisor's requirements

Always follow the guidelines outlined by your lecturer or supervisor or consult the instructions for authors (for journal articles), when conducting your literature review.

  • is an overview of the significant literature on a topic
  • typically includes a critical analysis of each work included
  • demonstrates the reviewers knowledge of the topic
  • is a list of citations of research sources (books, journal articles, websites etc) on a topic
  • includes a brief summary and analysis or evaluation of each citation = the annotation
  • a critical assessment of all research studies on a particular research question
  • has specific criteria for collecting and evaluating the literature
  • includes a synthesis of the findings of the included studies
  • This method developed by Griffith University's School of Environment bridges the gap between traditional narrative review methods and meta-analyses to enable students to produce results that are reliable, quantifiable and reproducible.

The requirements of narrative literature reviews are usually quite different than systematic reviews . However, you may be required to adopt some of the characteristics of a systematic approach when doing your literature review. Check the guidelines or criteria that have been set by your supervisor so you know what is expected of you.

What is a Literature Review?

A literature or narrative review is a comprehensive review and analysis of the published literature on a specific topic or research question. The literature that is reviewed contains: books, articles, academic articles, conference proceedings, association papers, and dissertations. It contains the most pertinent studies and points to important past and current research and practices. It provides background and context, and shows how your research will contribute to the field. 

A literature review should: 

  • Provide a comprehensive and updated review of the literature;
  • Explain why this review has taken place;
  • Articulate a position or hypothesis;
  • Acknowledge and account for conflicting and corroborating points of view

From  S age Research Methods

Purpose of a Literature Review

A literature review can be written as an introduction to a study to:

  • Demonstrate how a study fills a gap in research
  • Compare a study with other research that's been done

Or it can be a separate work (a research article on its own) which:

  • Organizes or describes a topic
  • Describes variables within a particular issue/problem

Limitations of a Literature Review

Some of the limitations of a literature review are:

  • It's a snapshot in time. Unlike other reviews, this one has beginning, a middle and an end. There may be future developments that could make your work less relevant.
  • It may be too focused. Some niche studies may miss the bigger picture.
  • It can be difficult to be comprehensive. There is no way to make sure all the literature on a topic was considered.
  • It is easy to be biased if you stick to top tier journals. There may be other places where people are publishing exemplary research. Look to open access publications and conferences to reflect a more inclusive collection. Also, make sure to include opposing views (and not just supporting evidence).

Introduction to Literature Reviews

Introduction.

  • Step One: Define
  • Step Two: Research
  • Step Three: Write
  • Suggested Readings

A literature review is a written work that :

  • Compiles significant research published on a topic by accredited scholars and researchers;
  • —Surveys scholarly articles, books, dissertations, conference proceedings, and other sources;
  • —Examines contrasting perspectives, theoretical approaches, methodologies, findings, results, conclusions.
  • —Reviews critically, analyzes, and synthesizes existing research on a topic; and,
  • Performs a thorough “re” view, “overview”, or “look again” of past and current works on a subject, issue, or theory.

From these analyses, the writer then offers an overview of the current status of a particular area of knowledge from both a practical and theoretical perspective.

Literature reviews are important because they are usually a  required  step in a thesis proposal (Master's or PhD). The proposal will not be well-supported without a literature review. Also, literature reviews are important because they help you learn important authors and ideas in your field. This is useful for your coursework and your writing. Knowing key authors also helps you become acquainted with other researchers in your field.

Look at this diagram and imagine that your research is the "something new." This shows how your research should relate to major works and other sources.

Chapter 1: Introduction

Learning objectives.

At the conclusion of this chapter, you will be able to:

  • Identify the purpose of the literature review in  the research process
  • Distinguish between different types of literature reviews

1.1 What is a Literature Review?

Pick up nearly any book on research methods and you will find a description of a literature review.  At a basic level, the term implies a survey of factual or nonfiction books, articles, and other documents published on a particular subject.  Definitions may be similar across the disciplines, with new types and definitions continuing to emerge.  Generally speaking, a literature review is a:

  • “comprehensive background of the literature within the interested topic area…” ( O’Gorman & MacIntosh, 2015, p. 31 ).
  • “critical component of the research process that provides an in-depth analysis of recently published research findings in specifically identified areas of interest.” ( House, 2018, p. 109 ).
  • “written document that presents a logically argued case founded on a comprehensive understanding of the current state of knowledge about a topic of study” ( Machi & McEvoy,  2012, p. 4 ).

As a foundation for knowledge advancement in every discipline, it is an important element of any research project.  At the graduate or doctoral level, the literature review is an essential feature of thesis and dissertation, as well as grant proposal writing.  That is to say, “A substantive, thorough, sophisticated literature review is a precondition for doing substantive, thorough, sophisticated research…A researcher cannot perform significant research without first understanding the literature in the field.” ( Boote & Beile, 2005, p. 3 ).  It is by this means, that a researcher demonstrates familiarity with a body of knowledge and thereby establishes credibility with a reader.  An advanced-level literature review shows how prior research is linked to a new project, summarizing and synthesizing what is known while identifying gaps in the knowledge base, facilitating theory development, closing areas where enough research already exists, and uncovering areas where more research is needed. ( Webster & Watson, 2002, p. xiii )

A graduate-level literature review is a compilation of the most significant previously published research on your topic. Unlike an annotated bibliography or a research paper you may have written as an undergraduate, your literature review will outline, evaluate and synthesize relevant research and relate those sources to your own thesis or research question. It is much more than a summary of all the related literature.

It is a type of writing that demonstrate the importance of your research by defining the main ideas and the relationship between them. A good literature review lays the foundation for the importance of your stated problem and research question.

Literature reviews:

  • define a concept
  • map the research terrain or scope
  • systemize relationships between concepts
  • identify gaps in the literature ( Rocco & Plathotnik, 2009, p. 128 )

The purpose of a literature review is to demonstrate that your research question  is meaningful. Additionally, you may review the literature of different disciplines to find deeper meaning and understanding of your topic. It is especially important to consider other disciplines when you do not find much on your topic in one discipline. You will need to search the cognate literature before claiming there is “little previous research” on your topic.

Well developed literature reviews involve numerous steps and activities. The literature review is an iterative process because you will do at least two of them: a preliminary search to learn what has been published in your area and whether there is sufficient support in the literature for moving ahead with your subject. After this first exploration, you will conduct a deeper dive into the literature to learn everything you can about the topic and its related issues.

Literature Review Tutorial

A video titled "Literature Reviews: An overview for graduate students." Video here: https://www.lib.ncsu.edu/tutorials/litreview/. Transcript available here: https://siskel.lib.ncsu.edu/RIS/instruction/litreview/litreview.txt

1.2 Literature Review Basics

An effective literature review must:

  • Methodologically analyze and synthesize quality literature on a topic
  • Provide a firm foundation to a topic or research area
  • Provide a firm foundation for the selection of a research methodology
  • Demonstrate that the proposed research contributes something new to the overall body of knowledge of advances the research field’s knowledge base. ( Levy & Ellis, 2006 ).

All literature reviews, whether they are qualitative, quantitative or both, will at some point:

  • Introduce the topic and define its key terms
  • Establish the importance of the topic
  • Provide an overview of the amount of available literature and its types (for example: theoretical, statistical, speculative)
  • Identify gaps in the literature
  • Point out consistent finding across studies
  • Arrive at a synthesis that organizes what is known about a topic
  • Discusses possible implications and directions for future research

1.3 Types of Literature Reviews

There are many different types of literature reviews, however there are some shared characteristics or features.  Remember a comprehensive literature review is, at its most fundamental level, an original work based on an extensive critical examination and synthesis of the relevant literature on a topic. As a study of the research on a particular topic, it is arranged by key themes or findings, which may lead up to or link to the  research question.  In some cases, the research question will drive the type of literature review that is undertaken.

The following section includes brief descriptions of the terms used to describe different literature review types with examples of each.   The included citations are open access, Creative Commons licensed or copyright-restricted.

1.3.1 Types of Review

1.3.1.1 conceptual.

Guided by an understanding of basic issues rather than a research methodology. You are looking for key factors, concepts or variables and the presumed relationship between them. The goal of the conceptual literature review is to categorize and describe concepts relevant to your study or topic and outline a relationship between them. You will include relevant theory and empirical research.

Examples of a Conceptual Review:

  • Education : The formality of learning science in everyday life: A conceptual literature review. ( Dohn, 2010 ).
  • Education : Are we asking the right questions? A conceptual review of the educational development literature in higher education. ( Amundsen & Wilson, 2012 ).

Figure 1.1 shows a diagram of possible topics and subtopics related to the use of information systems in education. In this example, constructivist theory is a concept that might influence the use of information systems in education. A related but separate concept the researcher might want to explore are the different perspectives of students and teachers regarding the use of information systems in education.

1.3.1.2 Empirical

An empirical literature review collects, creates, arranges, and analyzes numeric data reflecting the frequency of themes, topics, authors and/or methods found in existing literature. Empirical literature reviews present their summaries in quantifiable terms using descriptive and inferential statistics.

Examples of an Empirical Review:

  • Nursing : False-positive findings in Cochrane meta-analyses with and without application of trial sequential analysis: An empirical review. ( Imberger, Thorlund, Gluud, & Wettersley, 2016 ).
  • Education : Impediments of e-learning adoption in higher learning institutions of Tanzania: An empirical review ( Mwakyusa & Mwalyagile, 2016 ).

1.3.1.3 Exploratory

Unlike a synoptic literature review, the purpose here is to provide a broad approach to the topic area. The aim is breadth rather than depth and to get a general feel for the size of the topic area. A graduate student might do an exploratory review of the literature before beginning a synoptic, or more comprehensive one.

Examples of an Exploratory Review:

  • Education : University research management: An exploratory literature review. ( Schuetzenmeister, 2010 ).
  • Education : An exploratory review of design principles in constructivist gaming learning environments. ( Rosario & Widmeyer, 2009 ).

introduction on a literature review

1.3.1.4 Focused

A type of literature review limited to a single aspect of previous research, such as methodology. A focused literature review generally will describe the implications of choosing a particular element of past research, such as methodology in terms of data collection, analysis and interpretation.

Examples of a Focused Review:

  • Nursing : Clinical inertia in the management of type 2 diabetes mellitus: A focused literature review. ( Khunti, Davies, & Khunti, 2015 ).
  • Education : Language awareness: Genre awareness-a focused review of the literature. ( Stainton, 1992 ).

1.3.1.5 Integrative

Critiques past research and draws overall conclusions from the body of literature at a specified point in time. Reviews, critiques, and synthesizes representative literature on a topic in an integrated way. Most integrative reviews are intended to address mature topics or  emerging topics. May require the author to adopt a guiding theory, a set of competing models, or a point of view about a topic.  For more description of integrative reviews, see Whittemore & Knafl (2005).

Examples of an Integrative Review:

  • Nursing : Interprofessional teamwork and collaboration between community health workers and healthcare teams: An integrative review. ( Franklin,  Bernhardt, Lopez, Long-Middleton, & Davis, 2015 ).
  • Education : Exploring the gap between teacher certification and permanent employment in Ontario: An integrative literature review. ( Brock & Ryan, 2016 ).

1.3.1.6 Meta-analysis

A subset of a  systematic review, that takes findings from several studies on the same subject and analyzes them using standardized statistical procedures to pool together data. Integrates findings from a large body of quantitative findings to enhance understanding, draw conclusions, and detect patterns and relationships. Gather data from many different, independent studies that look at the same research question and assess similar outcome measures. Data is combined and re-analyzed, providing a greater statistical power than any single study alone. It’s important to note that not every systematic review includes a meta-analysis but a meta-analysis can’t exist without a systematic review of the literature.

Examples of a Meta-Analysis:

  • Education : Efficacy of the cooperative learning method on mathematics achievement and attitude: A meta-analysis research. ( Capar & Tarim, 2015 ).
  • Nursing : A meta-analysis of the effects of non-traditional teaching methods on the critical thinking abilities of nursing students. ( Lee, Lee, Gong, Bae, & Choi, 2016 ).
  • Education : Gender differences in student attitudes toward science: A meta-analysis of the literature from 1970 to 1991. ( Weinburgh, 1995 ).

1.3.1.7 Narrative/Traditional

An overview of research on a particular topic that critiques and summarizes a body of literature. Typically broad in focus. Relevant past research is selected and synthesized into a coherent discussion. Methodologies, findings and limits of the existing body of knowledge are discussed in narrative form. Sometimes also referred to as a traditional literature review. Requires a sufficiently focused research question. The process may be subject to bias that supports the researcher’s own work.

Examples of a Narrative/Traditional Review:

  • Nursing : Family carers providing support to a person dying in the home setting: A narrative literature review. ( Morris, King, Turner, & Payne, 2015 ).
  • Education : Adventure education and Outward Bound: Out-of-class experiences that make a lasting difference. ( Hattie, Marsh, Neill, & Richards, 1997 ).
  • Education : Good quality discussion is necessary but not sufficient in asynchronous tuition: A brief narrative review of the literature. ( Fear & Erikson-Brown, 2014 ).
  • Nursing : Outcomes of physician job satisfaction: A narrative review, implications, and directions for future research. ( Williams & Skinner, 2003 ).

1.3.1.8 Realist

Aspecific type of literature review that is theory-driven and interpretative and is intended to explain the outcomes of a complex intervention program(s).

Examples of a Realist Review:

  • Nursing : Lean thinking in healthcare: A realist review of the literature. ( Mazzacato, Savage, Brommels, 2010 ).
  • Education : Unravelling quality culture in higher education: A realist review. ( Bendermacher, Egbrink, Wolfhagen, & Dolmans, 2017 ).

1.3.1.9 Scoping

Tend to be non-systematic and focus on breadth of coverage conducted on a topic rather than depth. Utilize a wide range of materials; may not evaluate the quality of the studies as much as count the number. One means of understanding existing literature. Aims to identify nature and extent of research; preliminary assessment of size and scope of available research on topic. May include research in progress.

Examples of a Scoping Review:

  • Nursing : Organizational interventions improving access to community-based primary health care for vulnerable populations: A scoping review. ( Khanassov, Pluye, Descoteaux, Haggerty,  Russell, Gunn, & Levesque, 2016 ).
  • Education : Interdisciplinary doctoral research supervision: A scoping review. ( Vanstone, Hibbert, Kinsella, McKenzie, Pitman, & Lingard, 2013 ).
  • Nursing : A scoping review of the literature on the abolition of user fees in health care services in Africa. ( Ridde, & Morestin, 2011 ).

1.3.1.10 Synoptic

Unlike an exploratory review, the purpose is to provide a concise but accurate overview of all material that appears to be relevant to a chosen topic. Both content and methodological material is included. The review should aim to be both descriptive and evaluative. Summarizes previous studies while also showing how the body of literature could be extended and improved in terms of content and method by identifying gaps.

Examples of a Synoptic Review:

  • Education : Theoretical framework for educational assessment: A synoptic review. ( Ghaicha, 2016 ).
  • Education : School effects research: A synoptic review of past efforts and some suggestions for the future. ( Cuttance, 1981 ).

1.3.1.11 Systematic Review

A rigorous review that follows a strict methodology designed with a presupposed selection of literature reviewed.  Undertaken to clarify the state of existing research, the evidence, and possible implications that can be drawn from that.  Using comprehensive and exhaustive searching of the published and unpublished literature, searching various databases, reports, and grey literature.  Transparent and reproducible in reporting details of time frame, search and methods to minimize bias.  Must include a team of at least 2-3 and includes the critical appraisal of the literature.  For more description of systematic reviews, including links to protocols, checklists, workflow processes, and structure see “ A Young Researcher’s Guide to a Systematic Review “.

Examples of a Systematic Review:

  • Education : The potentials of using cloud computing in schools: A systematic literature review ( Hartmann, Braae, Pedersen, & Khalid, 2017 )
  • Nursing : Is butter back? A systematic review and meta-analysis of butter consumption and risk of cardiovascular disease, diabetes, and total mortality. ( Pimpin, Wu, Haskelberg, Del Gobbo, & Mozaffarian, 2016 ).
  • Education : The use of research to improve professional practice: a systematic review of the literature. ( Hemsley-Brown & Sharp, 2003 ).
  • Nursing : Using computers to self-manage type 2 diabetes. ( Pal, Eastwood, Michie, Farmer, Barnard, Peacock, Wood, Inniss, & Murray, 2013 ).

1.3.1.12 Umbrella/Overview of Reviews

Compiles evidence from multiple systematic reviews into one document. Focuses on broad condition or problem for which there are competing interventions and highlights reviews that address those interventions and their effects. Often used in recommendations for practice.

Examples of an Umbrella/Overview Review:

  • Education : Reflective practice in healthcare education: An umbrella review. ( Fragknos, 2016 ).
  • Nursing : Systematic reviews of psychosocial interventions for autism: an umbrella review. ( Seida, Ospina, Karkhaneh, Hartling, Smith, & Clark, 2009 ).

For a brief discussion see “ Not all literature reviews are the same ” (Thomson, 2013).

1.4 Why do a Literature Review?

The purpose of the literature review is the same regardless of the topic or research method. It tests your own research question against what is already known about the subject.

1.4.1 First – It’s part of the whole. Omission of a literature review chapter or section in a graduate-level project represents a serious void or absence of critical element in the research process.

The outcome of your review is expected to demonstrate that you:

  • can systematically explore the research in your topic area
  • can read and critically analyze the literature in your discipline and then use it appropriately to advance your own work
  • have sufficient knowledge in the topic to undertake further investigation

1.4.2 Second – It’s good for you!

  • You improve your skills as a researcher
  • You become familiar with the discourse of your discipline and learn how to be a scholar in your field
  • You learn through writing your ideas and finding your voice in your subject area
  • You define, redefine and clarify your research question for yourself in the process

1.4.3 Third – It’s good for your reader. Your reader expects you to have done the hard work of gathering, evaluating and synthesizes the literature.  When you do a literature review you:

  • Set the context for the topic and present its significance
  • Identify what’s important to know about your topic – including individual material, prior research, publications, organizations and authors.
  • Demonstrate relationships among prior research
  • Establish limitations of existing knowledge
  • Analyze trends in the topic’s treatment and gaps in the literature

1.4.4 Why do a literature review?

  • To locate gaps in the literature of your discipline
  • To avoid reinventing the wheel
  • To carry on where others have already been
  • To identify other people working in the same field
  • To increase your breadth of knowledge in your subject area
  • To find the seminal works in your field
  • To provide intellectual context for your own work
  • To acknowledge opposing viewpoints
  • To put your work in perspective
  • To demonstrate you can discover and retrieve previous work in the area

1.5 Common Literature Review Errors

Graduate-level literature reviews are more than a summary of the publications you find on a topic.  As you have seen in this brief introduction, literature reviews are a very specific type of research, analysis, and writing.  We will explore these topics more in the next chapters.  Some things to keep in mind as you begin your own research and writing are ways to avoid the most common errors seen in the first attempt at a literature review.  For a quick review of some of the pitfalls and challenges a new researcher faces when he/she begins work, see “ Get Ready: Academic Writing, General Pitfalls and (oh yes) Getting Started! ”.

As you begin your own graduate-level literature review, try to avoid these common mistakes:

  • Accepts another researcher’s finding as valid without evaluating methodology and data
  • Contrary findings and alternative interpretations are not considered or mentioned
  • Findings are not clearly related to one’s own study, or findings are too general
  • Insufficient time allowed to define best search strategies and writing
  • Isolated statistical results are simply reported rather than synthesizing the results
  • Problems with selecting and using most relevant keywords, subject headings and descriptors
  • Relies too heavily on secondary sources
  • Search methods are not recorded or reported for transparency
  • Summarizes rather than synthesizes articles

In conclusion, the purpose of a literature review is three-fold:

  • to survey the current state of knowledge or evidence in the area of inquiry,
  • to identify key authors, articles, theories, and findings in that area, and
  • to identify gaps in knowledge in that research area.

A literature review is commonly done today using computerized keyword searches in online databases, often working with a trained librarian or information expert. Keywords can be combined using the Boolean operators, “and”, “or” and sometimes “not”  to narrow down or expand the search results. Once a list of articles is generated from the keyword and subject heading search, the researcher must then manually browse through each title and abstract, to determine the suitability of that article before a full-text article is obtained for the research question.

Literature reviews should be reasonably complete, and not restricted to a few journals, a few years, or a specific methodology or research design. Reviewed articles may be summarized in the form of tables, and can be further structured using organizing frameworks such as a concept matrix.

A well-conducted literature review should indicate whether the initial research questions have already been addressed in the literature, whether there are newer or more interesting research questions available, and whether the original research questions should be modified or changed in light of findings of the literature review.

The review can also provide some intuitions or potential answers to the questions of interest and/or help identify theories that have previously been used to address similar questions and may provide evidence to inform policy or decision-making. ( Bhattacherjee, 2012 ).

introduction on a literature review

Read Abstract 1.  Refer to Types of Literature Reviews.  What type of literature review do you think this study is and why?  See the Answer Key for the correct response.

Nursing : To describe evidence of international literature on the safe care of the hospitalised child after the World Alliance for Patient Safety and list contributions of the general theoretical framework of patient safety for paediatric nursing.

An integrative literature review between 2004 and 2015 using the databases PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Scopus, Web of Science and Wiley Online Library, and the descriptors Safety or Patient safety, Hospitalised child, Paediatric nursing, and Nursing care.

Thirty-two articles were analysed, most of which were from North American, with a descriptive approach. The quality of the recorded information in the medical records, the use of checklists, and the training of health workers contribute to safe care in paediatric nursing and improve the medication process and partnerships with parents.

General information available on patient safety should be incorporated in paediatric nursing care. ( Wegner, Silva, Peres, Bandeira, Frantz, Botene, & Predebon, 2017 ).

Read Abstract 2.  Refer to Types of Literature Reviews.  What type of lit review do you think this study is and why?  See the Answer Key for the correct response.

Education : The focus of this paper centers around timing associated with early childhood education programs and interventions using meta-analytic methods. At any given assessment age, a child’s current age equals starting age, plus duration of program, plus years since program ended. Variability in assessment ages across the studies should enable everyone to identify the separate effects of all three time-related components. The project is a meta-analysis of evaluation studies of early childhood education programs conducted in the United States and its territories between 1960 and 2007. The population of interest is children enrolled in early childhood education programs between the ages of 0 and 5 and their control-group counterparts. Since the data come from a meta-analysis, the population for this study is drawn from many different studies with diverse samples. Given the preliminary nature of their analysis, the authors cannot offer conclusions at this point. ( Duncan, Leak, Li, Magnuson, Schindler, & Yoshikawa, 2011 ).

See Answer Key for the correct responses.

The purpose of a graduate-level literature review is to summarize in as many words as possible everything that is known about my topic.

A literature review is significant because in the process of doing one, the researcher learns to read and critically assess the literature of a discipline and then uses it appropriately to advance his/her own research.

Read the following abstract and choose the correct type of literature review it represents.

Nursing: E-cigarette use has become increasingly popular, especially among the young. Its long-term influence upon health is unknown. Aim of this review has been to present the current state of knowledge about the impact of e-cigarette use on health, with an emphasis on Central and Eastern Europe. During the preparation of this narrative review, the literature on e-cigarettes available within the network PubMed was retrieved and examined. In the final review, 64 research papers were included. We specifically assessed the construction and operation of the e-cigarette as well as the chemical composition of the e-liquid; the impact that vapor arising from the use of e-cigarette explored in experimental models in vitro; and short-term effects of use of e-cigarettes on users’ health. Among the substances inhaled by the e-smoker, there are several harmful products, such as: formaldehyde, acetaldehyde, acroleine, propanal, nicotine, acetone, o-methyl-benzaldehyde, carcinogenic nitrosamines. Results from experimental animal studies indicate the negative impact of e-cigarette exposure on test models, such as ascytotoxicity, oxidative stress, inflammation, airway hyper reactivity, airway remodeling, mucin production, apoptosis, and emphysematous changes. The short-term impact of e-cigarettes on human health has been studied mostly in experimental setting. Available evidence shows that the use of e-cigarettes may result in acute lung function responses (e.g., increase in impedance, peripheral airway flow resistance) and induce oxidative stress. Based on the current available evidence, e-cigarette use is associated with harmful biologic responses, although it may be less harmful than traditional cigarettes. (J ankowski, Brożek, Lawson, Skoczyński, & Zejda, 2017 ).

  • Meta-analysis
  • Exploratory

Education: In this review, Mary Vorsino writes that she is interested in keeping the potential influences of women pragmatists of Dewey’s day in mind while presenting modern feminist re readings of Dewey. She wishes to construct a narrowly-focused and succinct literature review of thinkers who have donned a feminist lens to analyze Dewey’s approaches to education, learning, and democracy and to employ Dewey’s works in theorizing on gender and education and on gender in society. This article first explores Dewey as both an ally and a problematic figure in feminist literature and then investigates the broader sphere of feminist pragmatism and two central themes within it: (1) valuing diversity, and diverse experiences; and (2) problematizing fixed truths. ( Vorsino, 2015 ).

Literature Review Tips for the Introduction and Discussion Sections

' src=

A literature review is a summary of studies related to a particular area of research. It identifies and summarizes all the relevant research conducted on a particular topic. It is important that your literature review is focused . Therefore, you should choose a limited number of studies that are central to your topic rather than trying to collect a wide range of studies that might not be closely connected.

Literature reviews help you accomplish the following:

  • Evaluate past research  Collecting relevant resources will help you see what research has already been done. This will also help avoid duplication.
  • Identify experts It is important to identify credible researchers who have knowledge in a given field, in order to seek their help if you get stuck with certain aspects of your research.
  • Identify key questions  Your ultimate aim is to bring something new to the conversation. Collecting resources will help you determine the important questions that need to be addressed.
  • Determine methodologies used in past studies Knowing how others have approached a particular topic will give you the opportunity to identify problems and find new ways to research and study a topic. If the reported methodology was successful, you can use it and save time that you would otherwise be spending on optimization.

Presenting Literature Review in the Introduction and Discussion Sections

There are many benefits to presenting literature reviews in the introduction and discussion sections of your manuscripts . However, there are differences in how you can present literature reviews in each section.

What Should be Included in the Literature Review of the Introduction Section?

The literature reviewed in the introduction should:

  • Introduce the topic
  • Establish the significance of the study
  • Provide an overview of the relevant literature
  • Establish a context for the study using the literature
  • Identify knowledge gaps
  • Illustrate how the study will advance knowledge on the topic

As you can see, literature review plays a significant role in the introduction section. However, there are some things that you should avoid doing in this section. These include:

  • Elaborating on the studies mentioned in the literature review
  • Using studies from the literature review to aggressively support your research
  • Directly quoting studies from the literature review

It is important to know how to integrate the literature review into the introduction in an effective way. Although you can mention other studies, they should not be the focus. Instead, focus on using the literature review to aid in setting a foundation for the manuscript.

What Goes in the Literature Review of the Discussion Section?

Literature reviews play an important role in the discussion section of a manuscript . In this section, your findings should be the focus, rather than those of other researchers. Therefore, you should only use the studies mentioned in the literature review as support and evidence for your study.

There are three ways in which you can use literature reviews in the discussion section:

  • To Provide Context for Your Study Using studies from the literature review helps to set the foundation for how you will reveal your findings and develop your ideas.
  • Compare your Findings to Other Studies You can use previous literature as a backdrop to compare your new findings. This helps describe and also advance your ideas.
  • State the Contribution of Your Study In addition to developing your ideas, you can use literature reviews to explain how your study contributes to the field of study.

However, there are three common mistakes that researchers make when including literature reviews in the discussion section. First, they mention all sorts of studies, some of which are not even relevant to the topic under investigation. Second, instead of citing the original article, they cite a related article that mentions the original article. Lastly, some authors cite previous work solely based on the abstract, without even going through the entire paper.

We hope this article helps you effectively present your literature review in both the introduction as well as the discussion section of your manuscript. You can also mention any other tips that will add to this article in the comments section below.

  • #5 Writing the Review
  • Citing Your Sources

WRITING THE REVIEW 

You've done the research and now you're ready to put your findings down on paper. When preparing to write your review, first consider how will you organize your review.

The actual review generally has 5 components:

Abstract  -  An abstract is a summary of your literature review. It is made up of the following parts:

  • A contextual sentence about your motivation behind your research topic
  • Your thesis statement
  • A descriptive statement about the types of literature used in the review
  • Summarize your findings
  • Conclusion(s) based upon your findings

Introduction :   Like a typical research paper introduction, provide the reader with a quick idea of the topic of the literature review:

  • Define or identify the general topic, issue, or area of concern. This provides the reader with context for reviewing the literature.
  • Identify related trends in what has already been published about the topic; or conflicts in theory, methodology, evidence, and conclusions; or gaps in research and scholarship; or a single problem or new perspective of immediate interest.
  • Establish your reason (point of view) for reviewing the literature; explain the criteria to be used in analyzing and comparing literature and the organization of the review (sequence); and, when necessary, state why certain literature is or is not included (scope)  - 

Body :  The body of a literature review contains your discussion of sources and can be organized in 3 ways-

  • Chronological -  by publication or by trend
  • Thematic -  organized around a topic or issue, rather than the progression of time
  • Methodical -  the focusing factor usually does not have to do with the content of the material. Instead, it focuses on the "methods" of the literature's researcher or writer that you are reviewing

You may also want to include a section on "questions for further research" and discuss what questions the review has sparked about the topic/field or offer suggestions for future studies/examinations that build on your current findings.

Conclusion :  In the conclusion, you should:

Conclude your paper by providing your reader with some perspective on the relationship between your literature review's specific topic and how it's related to it's parent discipline, scientific endeavor, or profession.

Bibliography :   Since a literature review is composed of pieces of research, it is very important that your correctly cite the literature you are reviewing, both in the reviews body as well as in a bibliography/works cited. To learn more about different citation styles, visit the " Citing Your Sources " tab.

introduction on a literature review

Learning Objectives

At the conclusion of this chapter, you will be able to:

  • Identify the purpose of the literature review in  the research process;
  • Distinguish between different types of literature reviews.

What is a Literature Review?

Pick up nearly any book on research methods and you will find a description of a literature review.  At a basic level, the term implies a survey of factual or nonfiction books, articles, and other documents published on a particular subject.  Definitions may be similar across the disciplines, with new types and definitions continuing to emerge.  Generally speaking, a literature review is a:

  • “comprehensive background of the literature within the interested topic area…” ( O’Gorman & MacIntosh, 2015, p. 31 [https://edtechbooks.org/-EaoJ] ).
  • “critical component of the research process that provides an in-depth analysis of recently published research findings in specifically identified areas of interest.” ( House, 2018, p. 109 [https://edtechbooks.org/-EaoJ] ).
  • “written document that presents a logically argued case founded on a comprehensive understanding of the current state of knowledge about a topic of study” ( Machi & McEvoy,  2012, p. 4 [https://edtechbooks.org/-EaoJ] ).

As a foundation for knowledge advancement in every discipline, it is an important element of any research project.  At the graduate or doctoral level, the literature review is an essential feature of thesis and dissertation, as well as grant proposal writing.  That is to say, “A substantive, thorough, sophisticated literature review is a precondition for doing substantive, thorough, sophisticated research…A researcher cannot perform significant research without first understanding the literature in the field.” ( Boote & Beile, 2005, p. 3 [https://edtechbooks.org/-EaoJ] ).  It is by this means, that a researcher demonstrates familiarity with a body of knowledge and thereby establishes credibility with a reader.  An advanced-level literature review shows how prior research is linked to a new project, summarizing and synthesizing what is known while identifying gaps in the knowledge base, facilitating theory development, closing areas where enough research already exists, and uncovering areas where more research is needed. ( Webster & Watson, 2002, p. xiii [https://edtechbooks.org/-EaoJ] )

A graduate-level literature review is a compilation of the most significant previously published research on your topic. Unlike an annotated bibliography or a research paper you may have written as an undergraduate, your literature review will outline, evaluate and synthesize relevant research and relate those sources to your own thesis or research question. It is much more than a summary of all the related literature.

It is a type of writing that demonstrate the importance of your research by defining the main ideas and the relationship between them. A good literature review lays the foundation for the importance of your stated problem and research question.

Literature reviews do the following:

  • define a concept
  • map the research terrain or scope
  • systemize relationships between concepts
  • identify gaps in the literature ( Rocco & Plathotnik, 2009, p. 128 [https://edtechbooks.org/-EaoJ] )

In the context of a research study, the purpose of a literature review is to demonstrate that your research question  is meaningful. Additionally, you may review the literature of different disciplines to find deeper meaning and understanding of your topic. It is especially important to consider other disciplines when you do not find much on your topic in one discipline. You will need to search the cognate literature before claiming there is “little previous research” on your topic.

Well developed literature reviews involve numerous steps and activities. The literature review is an iterative process because you will do at least two of them: a preliminary search to learn what has been published in your area and whether there is sufficient support in the literature for moving ahead with your subject. After this first exploration, you will conduct a deeper dive into the literature to learn everything you can about the topic and its related issues.

Literature Review Tutorial

introduction on a literature review

Literature Review Basics

An effective literature review must:

  • Methodologically analyze and synthesize quality literature on a topic
  • Provide a firm foundation to a topic or research area
  • Provide a firm foundation for the selection of a research methodology
  • Demonstrate that the proposed research contributes something new to the overall body of knowledge of advances the research field’s knowledge base. ( Levy & Ellis, 2006 [https://edtechbooks.org/-EaoJ] ).

All literature reviews, whether they are qualitative, quantitative or both, will at some point:

  • Introduce the topic and define its key terms
  • Establish the importance of the topic
  • Provide an overview of the amount of available literature and its types (for example: theoretical, statistical, speculative)
  • Identify gaps in the literature
  • Point out consistent finding across studies
  • Arrive at a synthesis that organizes what is known about a topic
  • Discusses possible implications and directions for future research

Types of Literature Reviews

There are many different types of literature reviews, however there are some shared characteristics or features that all share.  Remember a comprehensive literature review is, at its most fundamental level, an original work based on an extensive critical examination and synthesis of the relevant literature on a topic. As a study of the research on a particular topic, it is arranged by key themes or findings, which may lead up to or link to the  research question.  In some cases, the research question will drive the type of literature review that is undertaken.

The following section includes brief descriptions of the terms used to describe different literature review types with examples of each.   The included citations are open access, Creative Commons licensed or copyright-restricted.

Guided by an understanding of basic issues rather than a research methodology, the writer of a conceptual literature review is looking for key factors, concepts or variables and the presumed relationship between them. The goal of the conceptual literature review is to categorize and describe concepts relevant to the study or topic and outline a relationship between them, including relevant theory and empirical research.

Examples of a Conceptual Review:

  • The formality of learning science in everyday life: A conceptual literature review ( Dohn, 2010 [https://edtechbooks.org/-EaoJ] ).
  • Are we asking the right questions? A conceptual review of the educational development literature in higher education ( Amundsen & Wilson, 2012 [https://edtechbooks.org/-EaoJ] ).

An empirical literature review collects, creates, arranges, and analyzes numeric data reflecting the frequency of themes, topics, authors and/or methods found in existing literature. Empirical literature reviews present their summaries in quantifiable terms using descriptive and inferential statistics.

Examples of an Empirical Review:

  • Impediments of e-learning adoption in higher learning institutions of Tanzania: An empirical review ( Mwakyusa & Mwalyagile, 2016 [https://edtechbooks.org/-EaoJ] ).
  • Exploratory

The purpose of an exploratory review is to provide a broad approach to the topic area. The aim is breadth rather than depth and to get a general feel for the size of the topic area. A graduate student might do an exploratory review of the literature before beginning a more comprehensive one (e.g., synoptic).

Examples of an Exploratory Review:

  • University research management: An exploratory literature review ( Schuetzenmeister, 2010 [https://edtechbooks.org/-EaoJ] ).
  • An exploratory review of design principles in constructivist gaming learning environments ( Rosario & Widmeyer, 2009 [https://edtechbooks.org/-EaoJ] ).

This type of literature review is limited to a single aspect of previous research, such as methodology. A focused literature review generally will describe the implications of choosing a particular element of past research, such as methodology in terms of data collection, analysis, and interpretation.

Examples of a Focused Review:

  • Language awareness: Genre awareness-a focused review of the literature ( Stainton, 1992 [https://edtechbooks.org/-EaoJ] ).

Integrative

An integrative review critiques past research and draws overall conclusions from the body of literature at a specified point in time. As such, it reviews, critiques, and synthesizes representative literature on a topic in an integrated way. Most integrative reviews may require the author to adopt a guiding theory, a set of competing models, or a point of view about a topic.  For more description of integrative reviews, see Whittemore & Knafl (2005) [https://edtechbooks.org/-EaoJ] .

Examples of an Integrative Review:

  • Exploring the gap between teacher certification and permanent employment in Ontario: An integrative literature review ( Brock & Ryan, 2016 [https://edtechbooks.org/-EaoJ] ).
  • Meta-analysis

A subset of a systematic review, a meta-analysis takes findings from several studies on the same subject and analyzes them using standardized statistical procedures to pool together data. As such, it integrates findings from a large body of quantitative findings to enhance understanding, draw conclusions, and detect patterns and relationships. By gathering data from many different, independent studies that look at the same research question and assess similar outcome measures, data can be combined and re-analyzed, providing greater statistical power than any single study alone. It’s important to note that not every systematic review includes a meta-analysis but a meta-analysis can’t exist without a systematic review of the literature.

Examples of a Meta-Analysis:

  • Efficacy of the cooperative learning method on mathematics achievement and attitude: A meta-analysis research ( Capar & Tarim, 2015 [https://edtechbooks.org/-EaoJ] ).
  • Gender differences in student attitudes toward science: A meta-analysis of the literature from 1970 to 1991 ( Weinburgh, 1995 [https://edtechbooks.org/-EaoJ] ).

Narrative/Traditional

A narrative or traditional review provides an overview of research on a particular topic that critiques and summarizes a body of literature. Typically broad in focus, these reviews select and synthesize relevant past research into a coherent discussion. Methodologies, findings and limits of the existing body of knowledge are discussed in narrative form. This requires a sufficiently focused research question, and the process may be subject to bias that supports the researcher’s own work.

Examples of a Narrative/Traditional Review:

  • Adventure education and Outward Bound: Out-of-class experiences that make a lasting difference ( Hattie, Marsh, Neill, & Richards, 1997 [https://edtechbooks.org/-EaoJ] ).
  • Good quality discussion is necessary but not sufficient in asynchronous tuition: A brief narrative review of the literature ( Fear & Erikson-Brown, 2014 [https://edtechbooks.org/-EaoJ] ).

This specific type of literature review is theory-driven and interpretative and is intended to explain the outcomes of a complex intervention program(s).

Examples of a Realist Review:

  • Unravelling quality culture in higher education: A realist review ( Bendermacher, Egbrink, Wolfhagen, & Dolmans, 2017 [https://edtechbooks.org/-EaoJ] ).

This type of review tends to be a non-systematic approach that focuses on breadth of coverage rather than depth. It utilizes a wide range of materials and may not evaluate the quality of the studies as much as count the number. Thus, it aims to identify the nature and extent of research in an area by providing a preliminary assessment of size and scope of available research and may also include research in progress.

Examples of a Scoping Review:

  • Interdisciplinary doctoral research supervision: A scoping review ( Vanstone, Hibbert, Kinsella, McKenzie, Pitman, & Lingard, 2013 [https://edtechbooks.org/-EaoJ] ).

In contrast to an exploratory review, the purpose of a synoptic review is to provide a concise but accurate overview of all material that appears to be relevant to a chosen topic. Both content and methodological material is included. The review should aim to be both descriptive and evaluative as it summarizes previous studies while also showing how the body of literature could be extended and improved in terms of content and method by identifying gaps.

Examples of a Synoptic Review:

  • Theoretical framework for educational assessment: A synoptic review ( Ghaicha, 2016 [https://edtechbooks.org/-EaoJ] ).
  • School effects research: A synoptic review of past efforts and some suggestions for the future ( Cuttance, 1981 [https://edtechbooks.org/-EaoJ] ).

Systematic Review

A rigorous review that follows a strict methodology designed with a presupposed selection of literature reviewed, systematic reviews are undertaken to clarify the state of existing research, evidence, and possible implications that can be drawn.  Using comprehensive and exhaustive searching of the published and unpublished literature, searching various databases, reports, and grey literature, these reviews seek to produce transparent and reproducible results that report details of time frame and methods to minimize bias.  Generally, these reviews must include teams of at least 2-3 to allow for the critical appraisal of the literature.  For more description of systematic reviews, including links to protocols, checklists, workflow processes, and structure see “ A Young Researcher’s Guide to a Systematic Review [https://edtechbooks.org/-oF] “.

Examples of a Systematic Review:

  • The potentials of using cloud computing in schools: A systematic literature review ( Hartmann, Braae, Pedersen, & Khalid, 2017 [https://edtechbooks.org/-EaoJ] ).
  • The use of research to improve professional practice: a systematic review of the literature ( Hemsley-Brown & Sharp, 2003 [https://edtechbooks.org/-EaoJ] ).

Umbrella/Overview of Reviews

An umbrella review compiles evidence from multiple systematic reviews into one document. It therefore focuses on broad conditions or problems for which there are competing interventions and highlights reviews that address those interventions and their effects, thereby allowing for recommendations for practice. For a brief discussion see “ Not all literature reviews are the same [https://edtechbooks.org/-xZ] ” (Thomson, 2013).

Examples of an Umbrella/Overview Review:

  • Reflective practice in healthcare education: An umbrella review ( Fragknos, 2016 [https://edtechbooks.org/-EaoJ] ).

Why do a Literature Review?

The purpose of the literature review is the same regardless of the topic or research method. It tests your own research question against what is already known about the subject.

First – It’s part of the whole.

Omission of a literature review chapter or section in a graduate-level project represents a serious void or absence of a critical element in the research process.

The outcome of your review is expected to demonstrate that you:

  • can systematically explore the research in your topic area
  • can read and critically analyze the literature in your discipline and then use it appropriately to advance your own work
  • have sufficient knowledge in the topic to undertake further investigation

Second – It’s good for you!

  • You improve your skills as a researcher
  • You become familiar with the discourse of your discipline and learn how to be a scholar in your field
  • You learn through writing your ideas and finding your voice in your subject area
  • You define, redefine and clarify your research question for yourself in the process

Third – It’s good for your reader.

Your reader expects you to have done the hard work of gathering, evaluating, and synthesizing the literature.  When you do a literature review you:

  • Set the context for the topic and present its significance
  • Identify what’s important to know about your topic – including individual material, prior research, publications, organizations and authors.
  • Demonstrate relationships among prior research
  • Establish limitations of existing knowledge
  • Analyze trends in the topic’s treatment and gaps in the literature

So, why should you do a literature review?

  • To locate gaps in the literature of your discipline
  • To avoid reinventing the wheel
  • To carry on where others have already been
  • To identify other people working in the same field
  • To increase your breadth of knowledge in your subject area
  • To find the seminal works in your field
  • To provide intellectual context for your own work
  • To acknowledge opposing viewpoints
  • To put your work in perspective
  • To demonstrate you can discover and retrieve previous work in the area

Common Literature Review Errors

Graduate-level literature reviews are more than a summary of the publications you find on a topic.  As you have seen in this brief introduction, literature reviews are a very specific type of research, analysis, and writing.  We will explore these topics more in the next chapters.  Some things to keep in mind as you begin your own research and writing are ways to avoid the most common errors seen in the first attempt at a literature review.  For a quick review of some of the pitfalls and challenges a new researcher faces when he/she begins work, see “ Get Ready: Academic Writing, General Pitfalls and (oh yes) Getting Started! [https://edtechbooks.org/-GUc] ”.

As you begin your own graduate-level literature review, try to avoid these common mistakes:

  • Accepting another researcher’s finding as valid without evaluating methodology and data
  • Ignoring contrary findings and alternative interpretations
  • Providing findings that are not clearly related to one’s own study or that are too general
  • Allowing insufficient time to defining best search strategies and writing
  • Reporting rather than synthesizing isolated statistical results
  • Choosing problematic or irrelevant keywords, subject headings and descriptors
  • Relying too heavily on secondary sources
  • Failing to transparently report search methods
  • Summarizing rather than synthesizing articles

In conclusion, the purpose of a literature review is three-fold:

  • to survey the current state of knowledge or evidence in the area of inquiry,
  • to identify key authors, articles, theories, and findings in that area, and
  • to identify gaps in knowledge in that research area.

A literature review is commonly done today using computerized keyword searches in online databases, often working with a trained librarian or information expert. Keywords can be combined using the Boolean operators, “and”, “or” and sometimes “not”  to narrow down or expand the search results. Once a list of articles is generated from the keyword and subject heading search, the researcher must then manually browse through each title and abstract, to determine the suitability of that article before a full-text article is obtained for the research question.

Literature reviews should be reasonably complete and not restricted to a few journals, a few years, or a specific methodology or research design. Reviewed articles may be summarized in the form of tables and can be further structured using organizing frameworks such as a concept matrix.

A well-conducted literature review should indicate whether the initial research questions have already been addressed in the literature, whether there are newer or more interesting research questions available, and whether the original research questions should be modified or changed in light of findings of the literature review.

The review can also provide some intuitions or potential answers to the questions of interest and/or help identify theories that have previously been used to address similar questions and may provide evidence to inform policy or decision-making ( Bhattacherjee, 2012 [https://edtechbooks.org/-EaoJ] ).

Test Yourself

The purpose of a graduate-level literature review is to summarize in as many words as possible everything that is known about my topic.

A literature review is significant because in the process of doing one, the researcher learns to read and critically assess the literature of a discipline and then uses it appropriately to advance his/her own research.

Read the following abstract and choose the correct type of literature review it represents.

The focus of this paper centers around timing associated with early childhood education programs and interventions using meta-analytic methods. At any given assessment age, a child’s current age equals starting age, plus duration of program, plus years since program ended. Variability in assessment ages across the studies should enable everyone to identify the separate effects of all three time-related components. The project is a meta-analysis of evaluation studies of early childhood education programs conducted in the United States and its territories between 1960 and 2007. The population of interest is children enrolled in early childhood education programs between the ages of 0 and 5 and their control-group counterparts. Since the data come from a meta-analysis, the population for this study is drawn from many different studies with diverse samples. Given the preliminary nature of their analysis, the authors cannot offer conclusions at this point. ( Duncan, Leak, Li, Magnuson, Schindler, & Yoshikawa, 2011 [https://edtechbooks.org/-EaoJ] ).

In this review, Mary Vorsino writes that she is interested in keeping the potential influences of women pragmatists of Dewey’s day in mind while presenting modern feminist re readings of Dewey. She wishes to construct a narrowly-focused and succinct literature review of thinkers who have donned a feminist lens to analyze Dewey’s approaches to education, learning, and democracy and to employ Dewey’s works in theorizing on gender and education and on gender in society. This article first explores Dewey as both an ally and a problematic figure in feminist literature and then investigates the broader sphere of feminist pragmatism and two central themes within it: (1) valuing diversity, and diverse experiences; and (2) problematizing fixed truths.

introduction on a literature review

Aren’t all of us mini versions of Sherlock Holmes when browsing data and archives for a research piece? As we go through the process, a comprehensive literature review is an essential toolkit to make your research shine.

A literature review consists of scholarly sources that validate the content. Its primary objective is to offer a concise summary of the research and to let you explore relevant theories and methodologies. Through this review, you can identify gaps in the existing research and bridge them with your contribution. 

The real challenge is how to write an excellent literature review. Let’s learn.

What is the purpose of a literature review?

A literature review is an introduction to your research. It helps you put your perspective to the table, along with a summary of the theme.

What does my literature review communicate?

  • Explanation of your research: how the information was collected, the research method, the justification of the chosen data sources, and an overview of the data analysis.
  • Framework: the journey from where the concept began and how it is presented.
  • Connects the previous and current research: 

It presents the broader scope of your research by connecting it to the existing data and debates and underlining how your content fits the prevailing studies. 

In an era of information overload, a literature review must be well-structured. 

Let’s learn all about the structure and style of a literature review that’ll help you strengthen your research.

Literature review– structure and style

Begin with a question and end it with the solution– the key to structuring a literature review. It resembles an essay’s format, with the first paragraph introducing the readers to the topic and the following explaining the research in-depth.

The conclusion reiterates the question and summarizes the overall insights of your research. There’s no word count restriction. —it depends on the type of research. For example, a dissertation demands lengthy work, whereas a short paper needs a few pages. 

In a literature review, maintaining high quality is vital, with a focus on academic writing style. Informal language should be avoided in favor of a more formal tone. 

The content avoids contractions, clearly differentiating between previous and current research through the use of past and present tense. Wordtune assists in establishing a formal tone, enhancing your work with pertinent suggestions. This AI-powered tool ensures your writing remains genuine, lucid, and engaging.

Your friendly step-by-step guide to writing a literary review (with help from AI)

Do you find it challenging to begin the literature review? Don’t worry! We’re here to get you started with our step-by-step guide.

1. Narrow down the research scope

Simply begin with the question: What am I answering through my research?

Whether it’s cooking or painting, the real challenge is the prep-up for it rather than performing the task. Once you’re done, it smoothly progresses. Similarly, for your literature review, prepare the groundwork by narrowing down the research scope.

Browse and scoop out relevant data inclining well with your research. While you can’t cover every aspect of your research, pick a topic that isn’t too narrow nor too broad to keep your literature review well-balanced. 

2. Hunt relevant literature

The next question: Does this data align with the issue I’m trying to address?

As you review sources of information, hunt out the best ones. Determine which findings help in offering a focused insight on your topic. The best way to pick primary sources is to opt for the ones featured in reliable publications. You can also choose secondary sources from other researchers from a reasonable time frame and a relevant background.

For example, if your research focuses on the Historical Architecture of 18th-century Europe, the first-hand accounts and surveys from the past would hold more weight than the new-age publications. 

3. Observe the themes and patterns in sources

Next comes: What is the core viewpoint in most of the research? Has it stayed constant over time, or have the authors differed in their points of view?

Ensure to scoop out the essential aspects of what each source represents. Once you have collected all this information, combine it and add your interpretations at the end. This process is known as synthesis.

Synthesize ideas by combining arguments, findings and forming your new version.

4. Generate an outline

The next question: How can I organize my review effectively? When navigating multiple data sources, you must have noticed a structure throughout the research. Develop an outline to make the process easier. An outline is a skeletal format of the review, helping you connect the information more strategically.

Here are the three different ways to organize an outline– Chronologically, Thematically, or by Methodology.You can develop the outline chronologically, starting from the older sources and leading to the latest pieces. Another way of organizing is to thematically divide the sections and discuss each under the designated sub-heading.

You can even organize it per the research methods used by the respective authors. The choice of outline depends on the subject. For example, in the case of a science paper, you can divide the information into sections like introduction, types of equipment, method, procedure, findings, etc. In contrast, it’s best to present it in divisions based on timelines like Ancient, Middle Ages, Industrial revolutions, etc., for a history paper.

If you’re confused about how to structure the data, work with Wordtune.

Having a precise prompt is the key to getting the best results.

5. Start filling!

Your next question must be: Am I ready to compose all the parts of the literature review?

Once you’re ready with the basic outline and relevant sources, start filling in the data. Go for an introductory paragraph first to ensure your readers understand the topic and how you will present it. Ensure you clearly explain the section in the first sentence.

However, if beginning from the first paragraph seems intimidating, don’t worry! Add the main body content to the sub-headings, then jump to the introduction. 

Add headings wherever possible to make it more straightforward and guide your readers logically through different sources. Lastly, conclude your study by presenting a key takeaway and summarizing your findings. To make your task easier, work with Wordtune. It helps align your content with the desired tone and refine the structure.

6. Give attention to detail and edit

The last question: Am I satisfied with the language and content written in the literature review? Is it easy to understand?

Once you’re done writing the first draft of a literature review, it’s time to refine it. Take time between writing and reading the draft to ensure a fresh perspective. It makes it easier to spot errors when you disconnect from the content for some time. Start by looking at the document from a bird's eye to ensure the formatting and structure are in order. 

After reviewing the content format, you must thoroughly check your work for grammar, spelling, and punctuation. One of the best approaches to editing and proofreading is to use Wordtune . It helps simplify complex sentences, enhance the content quality, and gain prowess over the tonality.

The dos and don’ts of writing a literature review

Writing a stellar literature review requires following a few dos and don'ts. Just like Sherlock Holmes would never overlook a hint, you must pay attention to every minute detail while writing a perfect narrative. To help you write, below are some dos and don'ts to remember.

The dos and don’ts of writing a literature review

Composing a literature review demands a holistic research summary, each part exhibiting your understanding and approach. As you write the content, make sure to cover the following points:

  • Keep a historical background of the field of research. Highlight the relevant relation between the old studies and your new research.
  • Discuss the core issue, question, and debate of your topic.
  • Theories lay the foundation of research. While you’re writing a literature review, make sure to add relevant concepts and ideas to support your statements.
  • Another critical thing to keep in mind is to define complex terminologies. It helps the readers understand the content with better clarity. 

Examples of comprehensive literature reviews

Aren’t good examples the best way to understand a subject? Let’s look into a few examples of literature reviews and analyze what makes them well-written.

1. Critical Thinking and Transferability: A Review of the Literature (Gwendolyn Reece)

An overview of scholarly sources is included in the literature review, which explores critical thinking in American education. The introduction stating the subject’s importance makes it a winning literature review. Following the introduction is a well-defined purpose that highlights the importance of research.

As one keeps reading, there is more clarity on the pros and cons of the research. By dividing information into parts with relevant subheadings, the author breaks a lengthy literature review into manageable chunks, defining the overall structure.

Along with other studies and presented perspectives, the author also expresses her opinion. It is presented with minimal usage of ‘I,’ keeping it person-poised yet general. Toward the conclusion, the author again offers an overview of the study. A summary is further strengthened by presenting suggestions for future research as well. 

2. The Use of Technology in English Language Learning: A Literature Review

This literature review is thematically organized on how technology affects language acquisition. The study begins with an introduction to the topic with well-cited sources. It presents the views of different studies to help readers get a sense of different perspectives. After giving these perspectives, the author offers a personalized opinion.

One of the critical aspects that makes this a good literature review is a dedicated paragraph for definitions. It helps readers proceed further with a clear understanding of the crucial terminologies. There’s a comparison of the modern and previous studies and approaches to give an overall picture of the research.

Once the main body is composed, the author integrates recommendations for action-based tips. Thus, the literature review isn’t just summarizing the sources but offering actions relevant to the topics. Finally, the concluding paragraph has a brief overview with key takeaways.

Wordtune: your writing buddy!

A literature review demands the right balance of language and clarity. You must refine the content to achieve a formal tone and clear structure. Do you know what will help you the most? Wordtune !.

Nowadays, despite centuries of striving for equality, women still face higher levels of discrimination compared to men in nearly every aspect of life. Recently, this systemic inequality has manifested in cyberspace through the proliferation of abusive content that is even more aggressive than what one would expect in the 21st century. Various research disciplines are now attempting to characterise this new manifestation of misogyny. The endeavour to comprehend this phenomenon has resulted in a significant increase in publications from several fields, including Social Sciences, Arts and Humanities, Psychology, and Computer Science. This paper presents a systematic review of multidisciplinary research on misogyny from the years 1990 to 2022, encompassing a total of 2830 articles retrieved from the Scopus database as of December 31, 2022. The literature is thoroughly analysed using three approaches: bibliometric analysis, topic detection, and qualitative analysis of the documents. The findings suggest that the analysis of online misogyny has been the primary driver behind the exponential growth in publications in this field. Additionally, the results of the topic analysis and topic interaction reveal a limited connection between the areas of knowledge that are necessary to fully grasp this complex phenomenon.

Introduction.

Nowadays, regardless of centuries of fighting for equality, women continue to face a disproportionate amount of discrimination compared to men across various contexts. Women and girls encounter prejudice, sexist attitudes, open discrimination, and violence throughout their lives, while the extent of these experiences varies by location, identity, and culture. Disgust, intolerance, or entrenched prejudice, serving to legitimise women’s oppression, persist even in countries often alleged to be post-patriarchal, like the United States, Australia, and the United Kingdom (Manne, 2017 ). The all-pervasive form of hostility and aversion against women and girls is referred to as misogyny, a term derived from the Ancient Greek word “mĩsoguniã”, which means hatred of women. According to Allen ( 2021 ), misogyny has a disputed definition. Some authors offer a definition of misogyny that, in some respects, overlaps with the concept of sexism. For example, Code ( 2000 ) defines misogyny as any of the following acts or feelings: sexual and physical violence against women, exclusion of women, promotion of patriarchy, belittlement, and marginalisation of women. In this approach, the promotion of patriarchy, broadly conceptualised as a system or systems producing and reproducing gendered and intersectional inequalities, is clearly the spread of a sexist mentality. Here, sexism is linked to the acceptance of sex-role stereotypes and can manifest at various levels: individual, organisational, institutional, and cultural (VandenBos, 2015 ). In the same line of reasoning, Jukes ( 1993 ) states that misogyny can be obvious and explicit at times, but it can also be subtle and insidious. However, the subtle expression of misogyny is more linked to sexist attitudes than to the expression of hate. Other authors, such as Manne ( 2017 ), set out a clear distinction between sexism and misogyny. In her book, “Down Girl: The Logic of Misogyny”, Kate Manne ( 2017 ) describes misogyny as the patriarchal order’s “law enforcement” branch, which rewards “good” women who adhere to social norms while punishing those who disobey. Sexism, on the other hand, is viewed as the “justificatory” branch, which rationalises and justifies male dominance through beliefs, theories, stereotypes, and cultural narratives that portray women as naturally inferior. This conceptual debate is due to two reasons. First, the fact that misogyny is strictly linked to the concepts of patriarchy and sexism, and second, the evidence that our societies are facing new ways of conveying misogynistic content in the form of open denigration of women.

Focusing on the link between concepts that describe women’s discrimination, it is evident that the powerful dynamics of a patriarchal society contribute to the development of a sexist culture, and this leads to the oppression of women both in their personal lives and within societal institutions (Millet, 1970 ). Additionally, hostile and benevolent sexism (Glick and Fiske, 1997 ) functions to preserve patriarchy and conventional gender norms. Benevolent sexism manifests through subjectively positive attitudes towards women in traditional roles, encompassing protective paternalism, idealisation, and a desire for intimacy. On the other hand, hostile sexism is expressed in a blatant and resentful way toward women who violate traditional roles and includes the negative equivalents of each dimension of benevolent sexism: dominant paternalism, derogatory beliefs, and heterosexual hostility. The aforementioned patriarchal culture legitimises openly misogynistic expressions, which represent the most extreme manifestation of aggression against women.

In this complex dynamic, studies from different disciplines tend to use different terminology when examining hostility towards women. Specifically, research in psychology is more inclined to use terms related to sexism, especially in distinguishing between hostile and benevolent sexism, and the notion of patriarchy is extensively examined in social science, particularly in sociological studies. The concept of misogyny is more commonly used in communication studies and computational science. The findings reported in the Supplementary Material provide evidence of the emphasis of different disciplines on different concepts.

Regarding the emergence of new ways of transmitting misogynistic content, the rise of interactive social media has been widely considered (Moloney and Love, 2018 ; Rubio Martìn and Gordo Lòpez, 2021 ; Tranchese and Sugiura, 2021 ).

Misogyny on the internet is not a new phenomenon. Indeed, legislation pertaining to women’s online safety dates back to the Beijing Declaration in 1995. However, it was not until the events of Gamergate Footnote 1 (Massanari, 2020 ) in August 2014 that the mainstream media and academic research took notice. In fact, in the gaming community, 2014 saw the emergence of the controversy and online movement known as “Gamergate”. It started out as a reaction to questions about ethics in video game journalism, but it soon turned into a harassment campaign directed at female journalists. The movement brought attention to misogyny, sexism, and the need for diversity in the gaming industry.

With the development of social networks, the historical aversion to women has become articulated through new modes of communication and social interaction. While digital spaces have amplified female voices, online platforms have notoriously facilitated the spread of misogynistic content: women’s systematic inequality and discrimination have been replicated in cyberspace in the form of abusive content much more aggressive than we would have expected in the 21st century (Bates, 2021 ). The online realm provides ample opportunities for misogyny to be linguistically expressed in various ways, ranging from subtle forms such as social exclusion and discrimination to more severe forms like sexual objectification and violent threats (Anzovino et al., 2018 ). Studies examining online misogynistic discourse have employed different terminology, such as “gender cyber hatred” (Jane, 2017 ), “cyber harassment” (Citron, 2014 ), “technological violence” (Ostini and Hopkins, 2015 ), “gender trolling” (Mantilla, 2013 ), “e-bile”, and “gender hate speech” (Jane, 2015 ). Other scholars (see, for instance, Ging and Siapera, 2018 ) chose to use a broader definition of misogyny which almost always results in some form of harm, either directly, in the form of psychological, professional, or physical harm, or indirectly, making the internet a less equal, less safe, or less inclusive space for women and girls.

Our study aims to investigate the current state of research on misogyny. For this purpose, we focus on the scientific literature on this subject during the period between 1990 and 2022. To the best of our knowledge, our study is the first systematic review on misogyny which combines three approaches: bibliometrics, topic detection, and qualitative analysis of the documents.

For the bibliometric research, we first analyse the existing literature extracted from the Scopus database within the misogyny research field by exploiting bibliometric tools. Bibliometric analysis provides a systematic, transparent, and replicable manner to investigate extant literature in a given field and discover the progress of disciplinary research from a macro perspective, supporting future research directions. Using bibliometric methods, we explore the main lines of research in the scientific literature on misogyny and offer a summary of the research activity in terms of the volume of work and evolution over time, as well as in terms of the social, intellectual and conceptual structures of this research area.

Although bibliometric tools provide a broad overview of current research, they cannot deliver detailed insights into studies in the literature based on semantic content analysis. In order to conduct an in-depth semantic analysis, it is necessary to supplement bibliometric methods with text-mining techniques (Hu et al., 2014 ). In accordance, our work employs topic analysis based on the Latent Dirichlet Allocation method (LDA; Blei et al., 2003 ) in order to identify the most prevalent latent themes in misogyny literature. LDA is gaining popularity among scholars in diverse fields (Alghamdi and Alfalqi, 2015 ). Two important findings emerge from a topic model: a list of topics (i.e., clusters of words that appear frequently together) and a list of documents that are strongly associated with each topic. As a result, this method offers a probabilistic quantification of relevance for both the identification of topics and the classification of documents, making it useful for locating interpretable topics with semantic meaning and assigning these topics to literature documents (Tontodimamma et al., 2021 ). According to Suominen and Toivanen ( 2016 ), the main innovation of topic modelling in categorising scientific knowledge is that it essentially eliminates the need to fit knowledge that is brand-new to the world into definitions that are already well-established.

Finally, we complement the study with a qualitative analysis aimed to discover the sociological perspective of the literature on online misogyny, on the one hand, and the computational aspects, on the other hand.

Bibliometric analyses

Bibliographic dataset.

For the analysis, we use a bibliometric dataset covering the period 1990–2022, retrieved from the Scopus database on 31 December 2022. Since we focus on the broad spectrum of scientific research on misogyny, the bibliographic dataset was extracted by looking for publications containing terms related to the generic query “misogyn*” in the content of the title, abstract, and keywords. All types of publications were included in the search, and 2830 documents were retrieved. The top publication fields include Social Sciences, Arts and Humanities, Psychology, and Computer Science.

Information about document distribution by research field is given in the Supplementary Material , along with the document distribution by source and the ranking of the most productive countries and authors.

Research activity

The evolution over time of the number of published documents shows remarkable growth (see Fig. 1 ). We found out that the number of published documents has increased dramatically over time. Since 1992, it has been possible to distinguish two distinct phases. A gradual increase in publications occurred during the first phase, which lasted from 1990 to 2010. The second phase, from 2010 to 2022, has a higher growth rate, indicating increased interest. This finding aligns with the three-stage development theory (Price, 1963 ) of productivity on a particular subject. Small increments in the scientific literature are documented during the precursor period when some scholars begin publishing research on a new topic. The number of papers increases exponentially in the second phase as the topic expands and draws a growing number of scientists, as many facets of the subject remain unexplored. Finally, in the third phase, the curve aspect shifts from exponential to logistic, testifying to a stabilisation in production and a consolidation of the body of knowledge.

figure 1

Number of publications on misogyny per year: observed and expected temporal evolution according to exponential growth.

To verify the rapid increase, we fit an exponential growth curve to the data. The yearly rate of change in this model is 13.1%, demonstrating how research on misogyny might be cast in the second phase of development: although more research is being released, there is still space for improvement in many areas.

It is noteworthy to highlight that, as shown in the Supplementary Material , the research on misogyny from 1990 to 2002 follows a similar trend as sexism and has a slightly higher yearly growth rate compared to patriarchy. However, when considering only the five years prior to 2022, a more noticeable rise in the volume of published research on misogyny becomes evident, with a twofold increase in the number of published documents.

Social Structure of research on misogyny: collaboration network

To capture the essential characteristics of the misogyny research field, with a specific emphasis on collaborative efforts among different authors, we construct the authors’ collaboration network. We used the Bibliometrix R package, for performing network analysis and visualisation (Aria and Cuccurullo, 2017 ). Within the collaboration network, researchers act as nodes, and the connections between them (edges) represent co-authorships on articles. The node size is indicative of the authors’ productivity, measured in terms of the number of manuscripts authored or co-authored. The edges are weighted according to the frequency of co-authorship. Figure 2 visually illustrates the collaboration network among authors, highlighting the most significant cliques, each distinguished by different colours. The term “clique” is commonly employed to identify highly interconnected groups of elements, such as nodes or vertices, within a network. In our context, a “clique” signifies a group of authors who closely and frequently collaborate with one another compared to their counterparts, thereby creating a densely interconnected structure within the network. The most central scholars, with the highest number of connections, are Elisabetta Fersini, Paolo Rosso, Bilal Ghanem and Viviana Patti, who are also among the most proficient authors in the field of research on misogyny, as shown in the Supplementary Material . The noteworthy aspect is that the densest subgraphs link authors whose research falls under the computer science category.

Intellectual Structure of research on misogyny: citation analysis

The top five documents with the highest number of citations are: “Gamergate and The Fappening: How Reddit’s algorithm, governance, and culture support toxic technocultures” (Massanari, 2017 ), “Down girl: The logic of misogyny” (Manne, 2017 ), “Attitudinal antecedents of rape myth acceptance: A theoretical and empirical re-examination” (Lonsway and Fitzgerald, 1995 ), “Post-postfeminism?: new feminist visibilities in postfeminist times” (Gill, 2016 ) and “Beauty and Misogyny Harmful Cultural Practices in the West” (Jeffreys, 2005 ). These works investigate misogyny from various angles.

Manne’s book explores the logic of misogyny, which “primarily targets women because they are women in a man’s world ” (Manne, 2017 , p. 64). Manne argues that misogyny still exists in alleged post-patriarchal cultures and has taken different forms since legal equality, requiring women to be moral “givers” and validating a sense of entitlement among privileged men. Misogyny often takes the form of taking from women what they supposedly owe men and preventing women from competing for positions of power and authority traditionally held by men. In addition, Manne examines various examples of rape culture, including online harassment.

Considering attitudes toward sexual violence, Lonsway and Fitzgerald investigate the relationship between misogyny and rape myth acceptance. Here, rape myths can be defined as “attitudes and beliefs that are generally false but are widely and persistently held, and that serve to deny and justify male sexual aggression against women” (Lonsway and Fitzgerald, 1994 , pag. 134).

From a feminist perspective, Jeffreys argues that some Western beauty practices (e.g., makeup, high-heeled shoes, breast implants) should be included in the United Nations’ definition of harmful traditional/cultural practices due to the damaging effects they have on women’s health, the creation of sexual difference, and the enforcement of female deference. Gill’s article contends that it is crucial to examine how the media portrays feminism and to delve into the complexities of a cultural moment that seems to be characterised by a range of feminist ideologies (both contemporary and traditional), as well as a resurgence of anti-feminist attitudes and prevalent misogyny.

Massanari’s research centres on online misogyny and is based on a long-term participant-observation and ethnographic study of Reddit’s culture and community. The research specifically focuses on the #Gamergate and The Fappening cases. The Fappening involved the illegal distribution of nude photos of celebrities via anonymous image-board 4chan and Reddit, while #Gamergate was ostensibly about ethics in gaming journalism but became a campaign of harassment against female and minority game developers, journalists, and critics. The study highlights how Reddit’s design, algorithm, and platform politics implicitly support toxic technocultures, providing a fertile ground for anti-feminist and misogynistic movements to flourish. Online misogyny is also discussed in the papers with the highest number of local citations (i.e., citations from other documents within our bibliographic dataset): “#MasculinitySoFragile: Culture, structure, and networked misogyny” (Banet-Weiser and Miltner, 2016 ), “Back to the kitchen, cunt: Speaking the unspeakable about online misogyny” (Jane, 2014 ), and “Drinking male tears: language, the Manosphere, and networked harassment” (Marwick and Caplan, 2018 ).

Conceptual Structure of research on misogyny

To understand the conceptual structure of the research on misogyny, we initially performed an exploratory analysis of the textual content of the keywords chosen by the authors.

Figure 3 shows the most used keywords, after removing the term “misogyny”. Besides the extensive terms gender, feminism and sexism, we find keywords related to the phenomenon of violence against women, to the emerging theme of the Manosphere and to the classical theme of patriarchy and hegemonic masculinity. It is also worth noting the presence of several keywords strictly linked to the online diffusion of misogynistic content.

figure 3

Most used keywords.

To deepen the analysis, a conceptual structure map (see Fig. 4 ) of the literature on misogyny was created using the Bibliometrix R package (Aria and Cuccurullo, 2017 ), which enables performing multiple correspondence analysis (MCA, Greenacre and Blasius, 2006 ) and hierarchical clustering. MCA, in particular, allows the generation of a low-dimensional Euclidean representation of the original data matrix by performing a homogeneity analysis of the “documents by keywords” indicator matrix, which is constructed by taking into account a dummy variable for each keyword. The words are plotted on a two-dimensional plane, where closer words have a more consistent distribution across the documents.

figure 4

Conceptual map of research on misogyny.

The two dimensions of the maps that emerged from the MCA can be interpreted as follows. The first dimension separates keywords emphasising the problem of misogyny in general and on social media platforms (on the right) from those related to the methodological aspects of the automatic detection of misogynistic language (on the left). The second dimension separates keywords emphasising the problem of misogyny from a general point of view (on the upper) from those related to the Manosphere and Incels ( involuntary celibates ) and their presence on the Reddit platform (on the bottom). Figure 4 also displays the results obtained through a hierarchical cluster analysis carried out adopting the method of average linkage on the factorial coordinates obtained through MCA. Five clusters emerge from the conceptual structure map. The orange cluster refers to publications related to the automatic detection of misogynistic content through machine learning and deep learning techniques. The green cluster displays the connection between misogyny and hate speech and the exploitation of Natural Language Processing (NLP) methodologies to investigate these phenomena. The blue cluster refers to the intersectionality of research on misogyny. The red cluster is strictly linked to studies of the presence of misogynistic content on social media. Finally, the purple cluster is related to publications dealing with the topics of the Manosphere and the Incel phenomenon.

Research themes in misogyny literature

A topic modelling approach is exploited to investigate the textual content of title, abstract and authors’ keywords to give extra insight into multiple latent themes emerging from the literature on misogyny. To reveal the themes, research interests and trends of studies in the existing misogyny literature, we rely on the LDA model.

Topic analysis: LDA model

LDA is an unsupervised machine-learning-based algorithm allowing to discovery of latent (unobserved) “topics” in large unstructured text datasets (Blei et al., 2003 ). Previous research applied LDA to bibliometrics as an efficient tool for understanding a field’s rich underlying topical structure (see, among others, Suominen and Toivanen, 2016 , Tontodimamma et al., 2021 ). The idea behind LDA is that documents contain multiple topics, and each topic is represented as a probability distribution over terms in a fixed vocabulary, with different topics represented by different probabilities of words in the vocabulary. LDA generative process specifies a joint distribution of hidden and observed variables. The algorithm aims to estimate the posterior distribution of the hidden variables given the observed data, but exact inference is intractable, requiring approximate inference algorithms like sampling-based and variational algorithms (Blei et al., 2003 ; Steyvers and Griffiths, 2006 ). To employ LDA, the user needs to specify the number of latent topics in the corpus and two hyperparameters that control how documents and words contribute to topics. A detailed explanation of the LDA algorithm can be found in the studies by Blei ( 2012 ) and Steyvers and Griffiths ( 2006 ).

In our analysis, we use LDA to model a corpus with each document consisting of the publication title, abstract, and keywords. LDA analysis was performed through the Fitlda Matlab routine, available in the Text Analytics Toolbox (MATLAB, 2022 ).

Topic interpretation

The themes generated by LDA are hidden variables that require proper interpretation, typically done by examining the top keywords associated with each topic (Steyvers and Griffiths, 2006 ). To this end, Figs. 5 and 6 show the most important words for each topic, with importance determined by normalising the posterior word probabilities for each topic by the geometric mean of the posterior probabilities for the word across all topics. The topics are ranked based on their estimated likelihood of being observed in the entire dataset. Section 2 of the Supplementary Material contains the list of the most significant terms and their relevance measurements. The twelve selected topics address crucial areas of research on misogyny and can be summarised as follows.

figure 5

Word clouds for topics 1–6.

figure 6

Word clouds for topics 7–12.

Topic 1 revolves around a comprehensive discussion on the feminist perspective of the misogyny phenomenon and addresses the root causes of misogyny and gender-based discrimination. The primary focus is on patriarchal male gender privilege and its role in perpetuating misogyny. This topic covers a range of issues related to gender inequality, such as the leadership gap between men and women, women’s rights, and the intersection of misogyny with other forms of oppression.

Topic 2 focuses on how misogyny is expressed in literary works from the early and medieval periods to the modern era. Overall, this topic highlights the role of novels, prose, tales, and fiction in shaping societal attitudes and beliefs about gender and how this has influenced the treatment of women throughout history.

Along similar lines, Topic 3 centres on the study of misogyny in relation to the representation of women in films and on how it influences the portrayal of women on visual media.

Topic 4 is focused on the study of misogyny within the realm of politics and examines how misogyny can be perpetuated within political systems and movements. In particular, the inclusion of terms like “American”, “white”, and “altright” suggests that research included in this topic might focus on the ways in which misogyny is manifested in American politics, particularly within white nationalist and alternative-right movements.

Topic 5 is centred on the study of masculinity and how it relates to misogyny. In particular, the word “hegemonic” suggests that this topic may focus on how dominant forms of masculinity reinforce misogyny and gender-based discrimination.

Topic 6 pertains to the research on women’s rights, including reproductive rights, family law, and access to healthcare, particularly within legal and political systems and on how these systems can either promote or hinder gender equality.

The latent theme of Topic 7 seems to refer to a broad subject area that encompasses issues related to education, sexuality, and sexual identity. Additionally, the related terms suggest a focus on the ways in which sexuality is addressed within educational institutions, including schools and universities.

Topic 8 is a subject area that focuses on the study of digital misogyny, which refers to the ways in which sexism and gender-based discrimination are perpetuated through online and digital media platforms.

The set of words linked to Topic 9 clearly indicates studies focusing on the subject of sexual violence and harassment.

Research included in Topic 10 is related to the investigation of misogyny in the context of music and religion.

Topic 11 appears to be focused on the intersection of misogyny and racism, particularly as it relates to the misogynoir phenomenon.

Finally, Topic 12 deals with the identification and classification of online misogyny.

Topic interactions

By modelling each document as a mixture of several topics and each topic as a combination of words, the LDA technique assigns topics to documents. In our analysis, we awarded the top three document-topic probabilities to each document in this study as long as the probabilities are greater than 0.2. We developed a topic relationship network by considering the topic co-occurrence matrix. The topic network is depicted in Fig. 7 , along with node centrality measures. The nodes are coloured according to their degree, and the edges are weighted depending on co-occurrences. The stronger the link, the thicker the line. Edges with weights less than the average number of co-occurrences have been omitted. The investigation of the linkages reveals relationships between research fronts, emphasising the multidisciplinary character of research on misogyny. The highest degrees are associated with the first three topics, which encompass broader themes dealing with the feminist perspectives of patriarchal society (Topic 1) and the representation of women in literary works (Topic 2) and cinema (Topic 3). Moreover, the latter two topics show the strongest interconnection. Lower degrees are associated with more specialistic research fronts related to the presence of misogyny in music and religion, the misogynoir phenomenon, and the recent field of misogyny detection in computational sciences. In particular, the theme of automatic identification of misogynistic content (Topic 12) is only linked to the research dealing with digital misogyny (Topic 8). A high betweenness, measuring the extent to which the node is part of paths that connect an arbitrary pair of nodes in the network, is associated with Topics 5 and 6, dealing with the study of masculinity and how it relates to misogyny and to research on women rights, respectively. These findings suggest that those research areas are more effective and accessible in the network and form the densest bridges with other nodes.

figure 7

Topic co-occurence network for the publications on misogyny and nodes’ centrality measures.

Topic temporal evolution

The temporal evolution of the scientific productivity for each topic can be captured through Fig. 8 . The temporal trend of most topics agrees with exponential growth. However, looking at Topic 2, related to studies of misogyny in literary works, we notice how the number of publications in the last period falls below the number expected according to the exponential law. Conversely, the number of published documents for Topics 8 and 12 shows a sudden rise starting from 2018. This trend testifies to the increasing interest in the study of online misogyny and the related techniques for automatic detection and identification. A relatively more contained rise in the size of publications is recorded for Topics 10 related to the investigation of misogyny in the context of music and religions.

figure 8

The appearance and development of new fields of interest and innovative ideas in the research activity on misogyny are confirmed by the heatmaps provided in the Supplementary Material , which show the number of documents, by years, assigned to the identified topics.

Sociological research on online misogyny

To improve our comprehension of the ongoing research on the online dissemination of misogynistic content, we utilised a more specific selection query in our search of the original set of documents, which targeted terms associated with the online environment. We limited our search to articles published in journals categorised under the Social Science subject area. After analysing 277 articles, we identified 187 that were suitable for our study.

Among these documents, four articles provide a review of the literature on online misogyny from different perspectives. Moloney and Love ( 2018 ) review the way online misogyny is conceptualised in the social scientific literature within feminist media studies. The authors identify four different terms that are used to describe different types of online misogyny: online sexual harassment, gendertrolling, e-bile, and disciplinary rhetoric. They also examine the sociological perspective and introduce the concept of “virtual manhood acts” (VMAs), which is situated within the broader context of critical gender theory. VMAs are examples of technologically facilitated misogyny that occur in online social spaces: textual and visual cues are exploited to signal a masculine self, enforce traditional gender norms, oppress women, and restrict men to predefined gender roles. Bosch and Gil-Juarez ( 2021 ) conducted both a systematic review of 33 articles found in Web of Science and a traditional review of academic, institutional, and feminist-activist publications. Their findings show that the majority of aggressors in online gender-based violence are cis-hetero-patriarchal men, who are mostly known to the victims and are often partners or ex-partners. The types of violence range from sexual insults and threats to sexual and high-tech violence. Rubio Martìn and Gordo Lòpez ( 2021 ) provide an overview of the most recent academic literature within the feminist technosocial literature, specifically related to sexual and gender-based violence in digital environments. In addition to discussing the contemporary antecedents of this perspective and presenting current positions and the most representative studies on topics related to online misogyny, the authors demonstrate the potential of the feminist technosocial approach for analysing digital environments and their designs. The main conclusion drawn is that both the values of a misogynistic culture and the possibilities for its reproduction and dissemination are embedded in the design and architecture of digital platforms. The article also highlights the increasing relevance of hybrid realities that result from the synergies between the physical and digital realms, as they enable amplified discourses and actions of online misogyny. Faith ( 2022 ) investigates how gender, technology, and development are interconnected by analysing various works from different fields, including feminist technology studies, gender and development, feminist criminology, and ICT for development. The study also draws data from sources such as civil society, news reports, and international organisations, like the UN, to examine online violence. The author argues for a critical research approach to better understand the complex and opaque power dynamics that shape the digital economy and how it affects gender and development goals.

The articles on online misogyny, which were found in the Social Science category, underwent a manual annotation process to extract various pieces of information. Regarding the different methodologies and techniques used to investigate online misogyny, our findings indicate that discourse analysis and content analysis are the primary methodologies employed in social science literature. Several studies utilise in-depth interviews and surveys to examine the individuals targeted by and responsible for online misogyny. Additionally, digital ethnography, corpus linguistics, and network analysis are also employed. The most analysed social media platforms include Twitter, Reddit and Facebook. Further details on the methodological approaches and the social networks are provided in the Supplementary Material . The subsequent sections delve into details regarding target victims, misogynistic groups, and potential measures to counteract online misogyny.

Targets of online misogyny

Scholars studying online misogyny have identified various target groups that are particularly vulnerable to misogynistic content. These groups include female politicians, journalists, celebrities, influencers, musicians, gamers and developers, YouTubers, university students, and women who have been sexually assaulted. By focusing on specific target groups, research helps in achieving a more nuanced understanding of the ways in which online misogyny manifests and the specific harms that it causes.

Studies on online misogyny directed towards female politicians have concentrated on analysing the experiences of women from various countries, examining the types of misogynistic content directed towards them and the platforms on which it is disseminated. Silva-Paredes and Ibarra Herrera ( 2022 ), using a corpus-based critical discourse analysis, explore abuse received by a Chilean right-wing female politician. Phipps and Montgomery ( 2022 ) conducted an investigation into the portrayal of Nancy Pelosi as the monstrous feminine in the deeply misogynistic attack advertisements of Donald Trump’s 2020 presidential re-election campaign. In light of the prevalent misogynistic and anti-feminist depictions of Senator Hillary Clinton across all types of media, Ritchie ( 2013 ) examines how online media continues to have the power to create harmful representations of female politicians and the consequences for the political campaigns of women and for the democratic process as a whole. Focusing on Canadian politicians, Wagner ( 2022 ) discusses how online harassment is a gendered phenomenon. The study, drawing upon interviews with 101 people from diverse genders, racial/ethnic identities, sexual orientations, and partisan affiliations, shows that women are more aware of online harassment than men and how it succeeds in making women feel they are in a hostile political environment. Saluja and Thilaka ( 2021 ), analysing the Twitter discourse referring to three well-known female politicians in India, reveal similar findings, emphasising how female politicians are subjected to a different and distinct pattern of reception compared to their male counterparts. Instances of misogynistic or sexist hate speech and abusive language against female politicians in Japan are investigated in Fuchs and Schäfer ( 2021 ).

The research conducted by Chen et al. ( 2020 ) through in-depth interviews with 75 female journalists from Germany, India, Taiwan, the United Kingdom, and the USA revealed that those journalists frequently encounter online gendered harassment. The harassment, which includes sexist comments that criticise, attack, marginalise, stereotype, or threaten them based on their gender or sexuality, has led to some female journalists being subjected to misogynistic attacks and even threats of sexual violence. The study suggests that this kind of harassment limits their level of interaction with their audience without being attacked or sexually undermined.

By examining the findings of the qualitative in-depth interview of 48 female journalists, Similar findings are reported by Koirala ( 2020 ), whose study, based on the qualitative in-depth interview of 48 female journalists in Nepal, highlights how some of them tolerate harassment by being ‘strong like a man’, while many avoid social media platforms to keep free of such abusive behaviour. Along the same lines, Rego ( 2018 ) analyses Twitter conversations with Indian journalists and argues that social media platforms constitute convenient havens of harassment against assertive women.

Ghaffari ( 2022 ), analysing user-generated comments on the Instagram profile of a female American celebrity, shows how women are required to suppress their feelings and limit their authentic online presentation to maintain the outward countenance that matches the stereotypical gender roles in audiences’ state of mind. The research conducted by Döring and Mohseni ( 2019 ) supports these findings, focusing on video producers on YouTube. Their study found that female video producers are more likely to receive negative comments compared to male producers, but only if they display their sexuality or address feminist topics. However, if they conform to traditional gender role expectations, they do not experience this kind of negative feedback.

The emergence of female gamers in video game communities has led to a rise in misogynistic attacks against those who challenge the traditional hypermasculine culture of gaming. The 2014 #gamergate incident is a prime example of this, where a group of gamers opposed “Social Justice Warriors” who highlighted discrimination and exclusion in the gaming industry. Female gamers were subject to death threats, rape threats, and doxxing, where their private information was shared online (Tomkinson and Harper, 2015 ). The video gaming community has a long history of gender-based attacks on women, which serve to create a toxic environment for them when making and playing video games. According to Jenson and De Castell ( 2021 ), who approach the subject from a feminist perspective, video games have been predominantly masculine and gendered spaces. Repeated displays of aggression, referred to as “shock and awe”, perpetuate and legitimise gendered hostility. These displays also help to preserve exclusionary media practices designed to maintain the status quo.

The Manosphere

Numerous articles on online misogyny examine the Manosphere, a collection of websites and social media groups that endorse misogynistic beliefs. These networks are not uniform but consist of multiple misogynistic groups with differing perspectives and degrees of violence, which are associated with far-right, homophobic, and racist ideologies (Dickel and Evolvi, 2022 ). Despite their variations, all these groups portray feminism as innately discriminatory and threatening to men (Farci and Righetti, 2019 ). The Manosphere adheres to the beliefs of a ‘gynocentric order’ and the Red Pill ideology, a metaphor derived from the movie The Matrix, in which the protagonist’s eyes are opened to reality upon taking the “red pill”. Although these groups may have distinct beliefs, many members use the term misandry, referring to the hate against men, which has ideological and community-building functions. It reinforces a misogynistic belief system that portrays feminism as a movement that hates men and boys (Marwick and Caplan, 2018 ). The use of misandry caters to both extremist misogynistic subcultures and moderate men’s rights groups. It enables these groups to adopt the language of identity politics, positioning men as the silenced victims of reverse discrimination in all aspects of political, economic, and social life and solidifying their sense of entitlement (Farci and Righetti, 2019 ).

Men’s rights activists employ a personal action frame to construct a plausible but fictional narrative of men’s oppression (Carian, 2022 ). The movement against feminism revolves around advocating for men’s rights while denying that gendered violence exists (Garcìa-Mingo et al., 2022 ). The Manosphere engages in a crucial ideological effort that normalises, trivialises, and legitimises sexual violence against women in various forms (Garcìa-Mingo et al. 2022 ). Some of the primary themes of this ideology are: criticising and verbally abusing women, downplaying or not taking seriously accusations or reports of rape, depicting #MeToo as a feminist plot, portraying men as victims, and advocating for the restoration of patriarchal values (Dickel and Evolvi, 2022 ). Hopton and Langer ( 2022 ), analysing Twitter content to understand how the Manosphere constructs masculinity and femininity, identify three discursive strategies: co-opting discourses of oppression, naming power, and disavowal by disaggregation. These strategies are used to position men as victims, portray women as monstrous others, and re-establish gendered power hierarchies through continuous references to rape in their discourse.

One of the main groups in the Manosphere, the Incels, believes in a hetero-patriarchal racial hierarchy and justifies their lack of sexual activity through ideas rooted in biological determinism and victimisation by women and feminism (Lindsay, 2022 ). Scotto di Carlo’s analysis of Incels (Scotto di Carlo, 2023 ) reveals a conflation of apparently sarcastic metaphors, dark humour, and misogyny to describe women, as well as unique self-representations of forum participants that do not conform to typical ‘us vs them’ identity pattern (van Dijk, 1998 ): instead of highlighting the positive qualities of their in-group, the Incels describe themselves in a derogatory manner, leading to a spiral of self-pity and self-contempt that can foster a sense of brotherhood within the community. These findings stem from a content-discourse analysis of posts from threads specifically discussing women on an incel forum and from the study of nominations and predications of self-representations used in the ‘Introductions’ thread of the same forum. Halpin ( 2022 ), drawing on a qualitative analysis of comments made on a popular Incel discussion board, demonstrates how the group uses its perceived subordinate status to justify their misogyny and legitimise its degradation of women. Conducting an ethnographic content analysis of incel-identified subreddits and using femmephobia as a lens, Menzie ( 2022 ) examines how Incels employ heteropatriarchal conceptions of femininity to devalue women and to describe the social conditions that force them to remain celibate. The study focuses on the symbolic actors constructed by Incels, namely Stacy, who represents the most attractive women, Becky, who represents women of ordinary or moderate attractiveness, and Chad, who represents dominant alpha males. Five themes emerge from the analysis. First, Incels use these symbolic gendered actors to describe a sex deficit most men suffer, implying their own undesirability. Second, Incels’ femmephobia towards hyper-feminine women for not fitting heteropatriarchal requirements is evident in “Stacy”.Third, “Becky” shows a more flexible femmephobia towards women of different appearances who uphold “unrealistic standards” and date men more attractive than themselves or rely on feminism to cope with not attracting the same men as Stacy. Through “Chad”, the fourth topic examines the idea of masculinity, incorporating feelings of jealousy and recognition of victimisation under societal conditions that allow women to exploit men financially or emotionally. Finally, the analysis reveals how Incels prioritise partner display as a symbol of wealth. Along the same lines, Koller and Heritage ( 2020 ) analysed a textual corpus created from threads posted and commented on by Incels. The study examined keywords, word frequencies, and concordance lines to explore the representation of gendered social actors. The findings suggest that Incels position different groups of men in a hierarchy in which conventionally attractive men occupy the top position. Female social actors are not placed in a similar hierarchy. Furthermore, an additional appraisal analysis of the most frequently occurring male and female social actors reveals that men are judged as unable to function, while women are viewed as immoral, dishonest, and capable of causing harm to men.

Chang ( 2022 ), analysing the discourses circulating on a Reddit forum for self-proclaimed Incels, explores the perceptions created by the term “femoid”, a derogatory term generated by Incels to refer to women, constructing them as an abject “monstrous-feminine”, serving a dehumanising function and thus justifying the violence enacted upon them. Tranchese and Sugiura ( 2021 ) focus on the similarities between the language used in pornography and that of Incels, arguing that both are different manifestations of the same misogyny. Their study involves a linguistic analysis that compares a collection of posts from an Incel subreddit community with a reference collection of posts from 688 subreddits covering other subjects. From a different perspective, Byerly ( 2020 ) investigated news media language in the coverage of Incel behaviour associated with sexual aggression. The study employs qualitative textual analysis on a sample of 70 articles obtained using keyword combinations ‘incels and violence’, ‘incels and social media’, and ‘incels and sexism’ from 29 distinct news sources across 6 countries throughout the years 2018 and 2019. Research findings indicate that news stories emphasise the role of social media in helping Incels find each other and form online communities. Additionally, specific social media sites served as locations to amplify misogynistic attitudes and to boast about their murders. Speckhard et al. ( 2021 ) conducted a study that involved gathering information on Incels’ social and personal lives, adherence to incel ideology, opinions on incel-related violence, support for violent actions, and beliefs regarding the classification of Incels as violent extremists. The data was collected through a Google Forms survey that was distributed to active adult members of a prominent Incel forum. The final sample under analysis comprises 272 respondents who self-identify as Incels. The findings demonstrate that while most of them do not advocate violence and are non-violent, those who strongly hold misogynistic beliefs are more likely to endorse violent actions. Participation in Incel online forums, which validate their viewpoints, could also lead to an increase in their misogyny. O’Donnell and Shor ( 2022 ) investigated how misogynistic Incels discuss mass violence committed by their peers. Through qualitative content analysis of comments related to the 2018 Toronto van attack, in which self-declared Incel Alek Minassian drove a van into pedestrians, killing 10 and injuring 16, they found that a large majority of self-proclaimed Incels expressed support for such violence, as well as violence in general. Incels believed that mass violence was a means to achieve four main goals: gaining more attention, seeking revenge, reinforcing traditional masculinity, and bringing about political change.

MGTOW (Men Going Their Own Way), a separatist group within the Manosphere, also promotes a misogynistic agenda. Unlike Men’s Rights Activists and Incels, MGTOWs focus on individualistic and self-empowering actions, encouraging men to lead a self-sufficient life away from women. Jones et al. ( 2020 ), using content and thematic analyses of a corpus of tweets from three of the most active MGTOW users on Twitter, have linked the MGTOW ideology with toxic masculinity, showing that the online harassment it generates is deeply misogynistic and upholds heterosexual and hegemonic masculinity. The authors note that, although misogyny and violence produced by MGTOW are not extreme, the group’s appeals to rational thinking make them appear to be common sense. Wright et al. ( 2020 ) delve deeper into the structural underpinnings and nature of MGTOW debate within their discussion forums, including leadership, moderation, in-group dynamics, and the discursive form of debates, and how this contributes to the propagation of misogyny and different calls to action. The authors conducted a content analysis of comments in the official MGTOW website’s forum and a digital ethnographic approach. Their findings showed that discussions primarily revolve around women and the MGTOW community. When discussing women, users did so in an openly misogynistic way. When discussing MGTOW, conversations sought to define and rationalise it as an ideology, both for individuals and the collective. The authors also note that the communicative form was mainly communitarian, with strong group bonding, ties, and engagement.

Countering online misogyny

Strategies and tactics used by women to cope with and address gender violence online are diverse and sometimes activated simultaneously. Some of these strategies prioritise self-care and protection, while others focus on resistance and challenging such violence. From a self-care perspective, it is crucial to adopt mitigation measures that reduce harm and minimise risks, such as assessing online identities, adopting pseudonyms or collective identities, using masks, strengthening accounts, creating distance, silencing or erasing sensitive content (Bosch and Gil-Juarez, 2021 ). In the research by Chen et al. ( 2020 ), it is shown how female journalists have developed multiple strategies for coping with abuse, including modifying their social media postings, altering their reporting subjects, and utilising technological tools to prevent offensive comments on their public pages.

Merely prioritising self-care is insufficient; an active approach should be taken to resist and transform the current state of online misogyny. This involves engaging in actions that challenge the status quo and strive for meaningful change, with the ultimate goal of repoliticising the internet and social media with, for, and from a feminist perspective (Bosch and Gil-Juarez, 2021 ). From this standpoint, social media platforms can give space to the promotion of gender-based harassment but can also serve as crucial spaces for feminist education and activism and for the formation of a feminist counter-public that directly contests a misogynistic culture (Sills et al. 2016 ). In this perspective, Kurasawa et al. ( 2021 ) discuss a new form of feminist activism called evidentiary activism, which uses evidence of gender-based online violence (GBOV). Evidentiary activism engages with existing formal evidentiary cultures by advocating for legislative and regulatory reforms to address GBOV, promoting platform-based technological solutions, and challenging conventional notions of user privacy and anonymity. In addition, it involves contributing to and embracing informal evidentiary cultures, which use evidence as a tool for cultural and political mobilisation against GBOV. Strategies used include publicising instances of GBOV, highlighting the moral implications of such violence, and fostering feminist digital citizenship. As an example of online feminist activism, Kim ( 2017 ) explored the role of the 2015 hashtag #iamafeminist in promoting feminist identification and activism against misogyny in South Korea. The hashtag persisted for three months by addressing current gender issues and promoting activism both online and offline. The article by Shesterina and Fedosova ( 2021 ) examines the methods used by female bloggers to promote feminist ideas on Instagram. The authors found that while many posts are logically argued, female bloggers often use emotional manipulation and persuasion techniques to promote their ideas. The study identifies both the main topics in support of feminism, such as domestic violence and gender stereotypes, victim blaming, and the most common attitudes that female bloggers challenge in their posts (e.g., “gender roles are determined by nature”, “a woman must obey a man”, “female intelligence is worse than male”, “all women are hysterical”). The authors also describe the lexical means and rhetorical techniques commonly used in female blogs, such as metaphors, allusions, appeals, and rhetorical questions. The language used is generally colloquial, making texts easier to read, but it also includes harsh criticism and increased emotionality compared to traditional journalistic texts.

However, according to Jane ( 2016 ), taking matters into one’s own hands when faced with online harassment may have limited effectiveness and is not a sufficient solution to the problem of gendered cyber-hate. This approach shifts the responsibility from the perpetrators to the targets and the private sphere rather than addressing the broader social issue. The author suggests that a combination of feminist activism efforts, including a revised approach to collectivism, is needed to enact the necessary legislative and corporate changes to combat gendered online hate. The study by Davis and Santillana ( 2019 ) examines the potential and limitations of digital media activism in raising awareness about gender-based harassment using the case study of Las Morras, a Mexico City-based feminist media group. The study demonstrates the paradoxical role of networked digital media as an activist tool. While it rapidly circulated a critique of misogyny, it also attracted negative attention, leading to the group’s eventual demise due to doxing, trolling, and personal threats directed at its members.

Megalians, a cyberfeminist community in South Korea, utilised the technique of “mirroring” to combat online misogyny (Jeong and Lee, 2018 , Moon et al., 2022 , Yang and Lee, 2022 ). This practice involved mimicking the language of misogynistic online communities and reversing the roles of perpetrators and victims. Megalians also used parodies to subvert the humour and power dynamic that men often used to make fun of women. By appropriating and using the language of misogynists, they aimed to strip men of their ability to use misogynistic speech for their own entertainment. This approach also exposed the absurdity and ridiculousness of the misogynistic rhetoric. However, the success of mirroring is not clear-cut. In fact, while Megalians’ voices were heard in society, the strong message and crude language proved divisive and polarising (Kim, 2021 ).

An alternative strategy for addressing misogyny is to use social re-norming and appeal to the empathy of those engaging in harassing behaviour. The goal of re-norming is to challenge cultural attitudes and beliefs that tolerate or encourage violence against women and to promote new standards of behaviour that prioritise respect, equality, and safety for all individuals. One example of this approach is the experiment conducted by Whiley et al. ( 2023 ) on Twitter. Their experiment aimed to inform misogynistic offenders that their sexist language was disapproved of by the majority of people. However, this intervention did not result in a reduction in the number or frequency of sexist Tweets or users, nor did it affect the tone or emotional intensity of subsequent tweets. In contrast, research has demonstrated the efficacy of creative humour, such as that used by the IncelTears subreddit to ridicule Incels, in promoting (dis)affiliative and informative functions (Dynel, 2020 ).

Computational science research on online misogyny

In this section, we focus on documents on misogyny classified by Scopus in the “Computer Science” subject area. A total of 196 documents were found; 30 documents were excluded as they were off-topic. Two surveys were identified in the retrieved documents, which centre on the automated detection of online misogyny. In one survey, Shushkevich and Cardiff ( 2019 ) present an examination of techniques for identifying misogyny in social media through automation. Meanwhile, Sultana et al. ( 2021 ) conducted a systematic literature review of prior research to reveal different aspects of misogyny and sexist humour and to create a codebook for annotation purposes.

Automatic detection of misogyny

Manual classification of the retrieved articles reveals a wealth of valuable information regarding the automatic detection of misogyny. This includes details about the social networks that are being analysed, the primary techniques employed, and the availability of datasets.

In line with research in the social science area (see Section 4), Twitter (with 95 publications) and Reddit (with 46 publications) continue to be the most commonly used sources, even in the area of computational science. The number of studies dealing with Facebook and Instagram is very limited. Researchers frequently prioritise the study of Twitter (now rebranded X) and Reddit above other social media platforms due to their historically liberal provision of Application Programming Interface (API) access. Furthermore, Reddit, which has been described as ’a community of communities’ (Massanari, 2017 , p. 331), has a diverse array of subreddits that cater to different interests, some of which foster misogynistic beliefs. However, the new pricing plans for using the Twitter API, introduced in March 2023, are expected to significantly affect research. A survey conducted by the Coalition for Independent Technology Research Footnote 2 outlines the potential consequences of discontinuing free and affordable API access. These drawbacks include the disruption of research on the dissemination of harmful content. A similar survey on the impact of Reddit’s recent API changes Footnote 3 emphasises how researchers are concerned about interruptions in their research resulting from API modifications. It is worth noting that only one study (Semenzin and Bainotti, 2020 ) reports the results of research on Telegram, which, in fact, has become a widely used platform for the dissemination of abusive and misogynistic content due to its high degree of anonymity and limited content-moderation policies (Guhl and Davey, 2020 ).

The automatic detection of misogyny typically utilises various techniques, with pre-trained deep-learning models and multimodal models being the most commonly employed. Other techniques include machine learning algorithms such as SVM, Naïve Bayes, or Random Forest. Additionally, some documents rely on convolutional neural network models. More details on the published documents employing the different techniques are provided in the Supplementary Material .

Four articles employ the use of lexicons for automatic detection of misogyny. Attanasio and Pastor ( 2020 ) propose misogyny lexicons for automatic misogyny identification in order to improve sentence embedding similarity. Hurtlex (Bassignana et al. 2018 ), which is a lexicon of offensive, aggressive, and hateful words in more than 50 languages, is exploited for misogyny identification in the studies by Chiril et al. ( 2022 ) and Pamungkas et al. ( 2018 ). Kwarteng et al. ( 2022 ) created a specific lexicon around misogynoir.

Taxonomies and guidelines

When releasing annotated datasets, a crucial aspect is to clearly outline the guidelines for categorising misogynistic language. Four articles in the retrieved documents address this issue (Anzovino et al., 2018 , Guest et al., 2021 , Sultana et al., 2021 , Zeinert et al., 2021 ).

Sultana et al. ( 2021 ) proposed eleven categories to classify misogynistic remarks: Discredit (slurring over women with no other larger intention), Stereotyping (description of women’s physical appeal and/or comparisons to narrow standards), Sexual harassment (to physically assert power over women), Threats of violence (intent to physically assert power over women or to intimidate and silence women through threats of violence), Dominance (to preserve male control, protect male interest and exclude women from the conversation), Derailing (to justify abuse, reject male responsibility, and attempt to disrupt the conversation in order to refocus it), Victim blaming (blaming the victims for the problems they are facing), Mixed bias (gender bias might be mixed with other kinds of biases like religious or racial), Sexual objectification (evoke sexual imagery), and Damning (contains prayers to hurt women). Regarding the expression of misogyny using humour, this research proposes eight categories of jokes: Devaluation of personal characteristics, Women’s place in the private sphere, Violence against women, Feminist backlash, Sexual objectification, Excluding and/or objectifying humour, Transphobic Jokes and Cruel or Humiliation. All the categories proposed in Anzovino et al. ( 2018 ) are included in Sultana et al. ( 2021 ). The same occurs with categories proposed by Zeinert et al. ( 2021 ), except for the interesting concept of neosexism. Neosexism is a concept defined in Francine Tougas et al. ( 1999 ), and presents as the belief that women have already achieved equality and that discrimination of women does not exist. Neosexism was the most common form of misogyny present in the dataset of Zeinert et al. ( 2021 ). Guest et al. ( 2021 ) define four categories of misogynistic content: misogynistic pejoratives, descriptions of misogynistic treatment, acts of misogynistic derogation and gendered personal attacks against women.

Evaluation campaigns

A number of the documents on misogyny that fall within the Computer Science subject area were produced in connection with various evaluation campaigns. These campaigns include EVALITA (Evaluation of NLP and Speech Tools for Italian), IberLEF (Iberian Languages Evaluation Forum), SemEval (International Workshop on Semantic Evaluation), and FIRE (Forum for Information Retrieval Evaluation). The EVALITA campaign includes the Automatic Misogyny Identification (AMI) task (Fersini et al. 2018 ). The IberLEF annual campaign features the EXIST task, which is sEXism Identification in Social neTworks (Rodrìguez-Sanchez et al. 2021 ). SemEval has a task called MAMI, which is Multimedia Automatic Misogyny Identification (Fersini et al., 2022 ). Lastly, FIRE includes the Arabic Misogyny Identification (ArMI) task (Mulki and Ghanem, 2022 ).

Thanks to these evaluation campaigns, datasets for automatic misogyny detection in multiple languages are now available. Specifically, the AMI task made available two datasets, in English and Italian, downloaded from Twitter. The EXIST task provided datasets of tweets in both English and Spanish. The dataset released for the MAMI challenge comprises memes that were downloaded from popular social media platforms such as Twitter and Reddit, as well as from websites dedicated to meme creation and sharing. Lastly, the ArMI task provided a dataset of tweets written in Modern Standard Arabic (MSA) and various Arabic dialects.

The bibliometric analysis reveals that research on misogyny has witnessed exponential growth from 2010 to 2022. This growth can be attributed to various areas of research, but one prominent factor contributing to this trend is the increased attention given to the online dissemination of hate towards women. Several findings support this initial conclusion.

Firstly, the analysis indicates that the most productive authors in the field of misogyny research come from the area of computer science. This suggests that experts in this field have been actively investigating and publishing on the topic, further driving the growth of research in this area.

Moreover, examining the topics covered in the analysed documents provides additional evidence for the influence of online misogyny. Topic 8, which is related to digital misogyny, and Topic 12, which focuses on the automatic identification of misogyny in social media, have experienced significantly higher growth compared to the broader field of misogyny research (as depicted in Fig. 8 ). This finding indicates that the study of misogyny in online platforms and the development of methods to detect misogyny in social media have gained considerable attention within the research community.

The major role that online misogyny plays in the development of the area supports the idea that the research seeks to delineate the contours of a new face of misogyny, the latest manifestation of hate towards women which is expressed more crudely and more openly on social networks because they facilitate anonymity and a greater distance from the victims.

Another conclusion drawn from the analysis of the conceptual structure of misogyny research (Fig. 4) and the interactions between topics (Fig. 7 ) is that the research focused on the automatic detection of misogyny in online platforms (Topic 12) exhibits weak connections with other conceptual areas that address different aspects of the phenomenon. This area of research only demonstrates some conceptual relation to the broader study of online misogyny (Topic 8). This presents a significant challenge, considering that qualitative analysis of sociological research emphasises the growing relevance of hybrid realities resulting from the synergies between the physical and digital realms, not just in violence against women but also in specific domains such as politics. Moreover, the lack of relationship between Topic 12, which focuses on the automatic detection of misogyny, and Topic 9, which explores violence against women and the concept of Manosphere (primarily a digital phenomenon), is particularly noteworthy. This suggests that research in the computational science domain may not be adequately addressing the most extreme manifestations of online misogyny. Furthermore, it also indicates that the tools offered by computational linguistics are underutilised in social science-led research.

In general, the absence of stronger connections between certain topics that attract the attention of various disciplines could be seen as a sign of the practical challenges encountered in interdisciplinary research. For instance, Topic 6, which focuses on the study of women’s rights within legal and political systems, exhibits very weak relationships with Topics 8 and 12, despite qualitative sociological research emphasising the need to consider the new dynamics emerging in virtual spaces. Another illustration can be found in the qualitative review of computational science literature. It becomes apparent that this research area relies on the definition of taxonomies that would benefit from clarification through collaboration with social science research. For instance, the inclusion of stereotypes against women as part of the types of misogyny raises the question of whether the concept of misogyny should be reserved for the most extreme forms of hatred or should encompass the wide range of sexist attitudes and gender symbolic constructions derived from a patriarchal culture.

The main conclusion drawn from this work is that research across different disciplines is addressing a new facet of misogyny, a revitalised version of outdated beliefs about women’s inferiority that circulate in novel forms within the online realm. Understanding the characteristics and functions of this new expression of misogyny poses a challenge that necessitates an interdisciplinary approach, leveraging the strengths of different areas of knowledge to effectively address it.

The above-mentioned lack of collaboration between different areas prevents the establishment of connections that would enrich the analysis of the way misogyny is disseminated today in both the virtual and real world. For example, social science knowledge in combination with computational discourse analysis or NLP technologies could be used to study the connections and similarities between agents disseminating misogyny online and mainstream social actors such as political parties or religious organisations. In the same way, the similarity between misogynist discourses and those of left-leaning feminists in open battle against other fractions of the feminist movement could also be monitored and would allow for a more complex view of the phenomenon. For both approaches, it is necessary that social science knowledge strongly rooted in the study of social relations be combined with the new methodologies that computer science offers for the analysis of discourse produced naturally in digital or real communicative exchanges, such as in parliaments, rallies or interviews.

Introduction Heart Failure is a clinical syndrome characterized by a series of symptoms such as dyspnea, orthopnea and edema in the lower limbs. This pathology continues to have a high prevalence despite advances in pharmacotherapy and device therapy and given that it is a pathology that significantly impairs the quality of life of patients, the implementation of care is of vital importance. However, these are underused due to lack of knowledge on the part of health personnel and also due to poor implementation in the different health providers.

Objective An exploratory review of the literature was carried out regarding the benefits of palliative care in patients with advanced heart failure, in order to synthesize the available and updated evidence.

Methodology Searched for articles published from 2017 to 2022 related to palliative care in patients with heart failure and using the PRISMA 2020 methodology for this study. This inquiry of articles was carried out in the following databases: UpToDate, PubMed, MESH, PMC (US National Library of Medicine National Institutes of health).

Results A total of 5 articles were obtained, from which they concluded that palliative care has a positive impact on the quality of life of patients with heart failure, there was a lower rate of hospital readmissions, improvements in physical, psychological and existential.
