Introduction

Narrative reviews are a type of knowledge synthesis grounded in a distinct research tradition. They are often framed as non-systematic, which implies that there is a hierarchy of evidence placing narrative reviews below other review forms. 1 However, narrative reviews are highly useful to medical educators and researchers. While a systematic review often focuses on a narrow question in a specific context, with a prespecified method to synthesize findings from similar studies, a narrative review can include a wide variety of studies and provide an overall summary, with interpretation and critique. 1 Examples of narrative review types include state-of-the-art, critical, and integrative reviews, among many others.

Foundations

Narrative reviews are situated within diverse disciplines in the social sciences and humanities. Most forms of narrative reviews align with subjectivist and interpretivist paradigms. These worldviews emphasize that reality is subjective and dynamic. They contrast with the positivist and post-positivist worldviews that are the foundations of systematic reviews: a single reality can be known through experimental research. Unlike systematic reviews, narrative reviews offer researchers the ability to synthesize multiple points of view and harness unique review team perspectives, which will shape the analysis. Therefore, insights gained from a narrative review will vary depending on the individual, organizational, or historical contexts in which the review was conducted. 1 - 5

Why Choose a Narrative Review?

Narrative reviews allow researchers to describe what is known on a topic while conducting a subjective examination and critique of an entire body of literature. Authors can describe the topic's current status while providing insights on advancing the field, new theories, or current evidence viewed from different or unusual perspectives. 3 Therefore, such reviews can be useful by exploring topics that are under-researched as well as for new insights or ways of thinking regarding well-developed, robustly researched fields.

Narrative reviews are often useful for topics that require a meaningful synthesis of research evidence that may be complex or broad and that require detailed, nuanced description and interpretation. 1 See Boxes 1 and 2 for resources on writing a narrative review as well as a case example of a program director's use of a narrative review for an interprofessional education experience. This Journal of Graduate Medical Education (JGME) special review series will continue to use the Case of Dr. Smith to consider the same question using different review methodologies.

Box 1 The Case of Dr. Smith

Dr. Smith, a program director, has been tasked to develop an interprofessional education (IPE) experience for the residency program. Dr. Smith decides that conducting a literature review would be a savvy way to examine the existing evidence and generate a publication useful to others. Using PubMed and a general subject search with “interprofessional education,” Dr. Smith identifies 24 000 matches. Dr. Smith begins to randomly sample the papers and notes the huge diversity of types and approaches: randomized trials, qualitative investigations, critical perspectives, and more.

Dr. Smith decides to do a meta-narrative review, because she notes that there are tensions and contradictions in the ways in which IPE is discussed by different health professions education communities, such as in nursing literature vs in medical journals.

Process and Rigor

While each type of narrative review has its own associated markers of rigor, the following guidelines are broadly applicable to narrative reviews and can help readers critically appraise their quality. These principles may also guide researchers who wish to conduct narrative reviews. When engaging with a narrative review as a reader or a researcher, scholars are advised to be conversant with the following 5 foundational elements of narrative reviews.

Rationale for a Narrative Review

First, scholars should consider the framing of the research question. Does the topic being studied align with the type of knowledge synthesis performed through a narrative review? Authors should have a clear research question and a specific audience target. Authors should also provide a rationale for why a narrative review method was chosen. 6 The manuscript should include the initial research question as well as details about any iterative refinements to the question.

Clarity of Boundaries, Scope, and Definitions

Second, although narrative reviews do not typically involve strict predetermined inclusion or exclusion criteria, scholars should explicitly demarcate the boundaries and scope of their topic. They should also clearly define key terms related to the topic and research question and any definitions used. Authors should elaborate why they chose a particular definition if others were available. As narrative reviews are flexible, the initial scope may change through the review process. In such circumstances, authors should provide reasonable justification for the evolution of inclusion and exclusion criteria and a description of how this affected the literature search.

Justification for Inclusion and Exclusion Criteria

Third, authors of narrative reviews should explain which search terms and databases were included in the synthesis and why. For example, did authors include research studies from a particular database, time frame, or study design? Did they include commentaries or empirical articles? Did they include grey literature such as trade publications, reports, or digital media? Each of the authors' choices should be outlined with appropriate reasoning. 7 Narrative reviews tend to be iterative and involve multiple cycles of searching, analysis, and interpretation. High-quality narrative reviews usually include pivotal or seminal papers that address the phenomenon of interest and other manuscripts that are relevant to the research question.

Reflexivity and a Saturation/Sufficiency Statement

Fourth, narrative reviews should clearly specify any factors that may have shaped the authors' interpretations and analysis. One fundamental distinction between narrative and non-narrative reviews is that narrative reviews explicitly recognize that they may not include all relevant literature on a topic. Since narrative reviews do not aim to be inclusive of all literature addressing the phenomenon of interest, a justification for the selection of manuscripts must be included. Authors should carefully outline how researchers conducted analyses and how they determined that sufficient analysis and interpretation was achieved. This latter concept is similar to considerations of saturation or thematic sufficiency in primary qualitative research. 8

Details on Analysis and Interpretation

Lastly, since several different categories of reviews fall under the narrative review umbrella, the analysis conducted in a narrative review varies by type. Regardless of the type of narrative review carried out, authors should clearly describe how analyses were conducted and provide justification for their approach. Narrative reviews are enhanced when researchers are explicit about how their perspectives and experiences informed problem identification, interpretation, and analysis. Given that authors' unique perspectives shape the selection of literature and its interpretation, narrative reviews may be reproduced, but different authors will likely yield different insights and interpretations.

Distinctive Methods and Subtypes

The narrative review has been commonly framed as an umbrella term that includes several different subtypes of reviews. These narrative medicine subtypes share the goals of deepening an understanding of a topic, while describing why researchers chose to explore and analyze the topic in a specific way.

There are several subtypes of narrative reviews with distinctive methodologies; each offers a unique way of approaching the research question and analyzing and interpreting the literature. This article will describe some common narrative review types that will also be discussed in upcoming JGME special articles on reviews: state-of-the-art , meta-ethnographic , critical , and theory integration reviews.

A state-of-the-art review attempts to summarize the research concerning a specific topic along a timeline of significant changes in understanding or research orientations. By focusing on such turning points in the history of evolving understandings of a phenomenon, state-of-the-art reviews offer a summary of the current state of understanding, how such an understanding was developed, and an idea of future directions. A state-of-the art review seeks to offer a 3-part description: where are we now in our understanding, how did we get here, and where should we go next?

A meta-ethnographic review involves choosing and interpreting qualitative research evidence about a specific topic. Working exclusively with qualitative data, this type of knowledge synthesis aims to generate new insights or new conclusions about a topic. It draws together insights and analyses from existing publications of qualitative research to construct new knowledge that spans across these individual, and often small scale, studies.

A meta-narrative review seeks to explore and make sense of contradictions and tensions within the literature. A meta-narrative review maps how a certain topic is understood in distinct ways, conducts a focused search to describe and compare narratives, and then seeks to make sense of how such narratives are interpreted across different disciplines or historical contexts, as part of the analysis. 9

A critical review is a narrative synthesis of literature that brings an interpretative lens: the review is shaped by a theory, a critical point of view, or perspectives from other domains to inform the literature analysis. Critical reviews involve an interpretative process that combines the reviewer's theoretical premise with existing theories and models to allow for synthesis and interpretation of diverse studies. First, reviewers develop and outline their interpretive theoretical position, which is informed by individual knowledge and experience. Next, a noncomprehensive search is completed to capture and identify dominant themes focused on a research question. 8 , 10

An integrative review typically has 1 of 2 different orientations. Empirical integrative reviews analyze and synthesize publications of evidence-based studies with diverse methodologies. In contrast, theoretical integrative reviews conduct an analysis of the available theories addressing a phenomenon, critically appraise those theories, and propose an advancement in the development of those theories. Both types of integrative reviews follow a multistage approach including problem identification, searching, evaluation, analysis, and presentation. 11

Strengths and Weaknesses

Narrative reviews have many strengths. They are flexible and practical, and ideally provide a readable, relevant synthesis of a diverse literature. Narrative reviews are often helpful for teaching or learning about a topic because they deliver a general overview. They are also useful for setting the stage for future research, as they offer an interpretation of the literature, note gaps, and critique research to date.

Such reviews may be useful for providing general background; however, a more comprehensive form of review may be necessary. Narrative reviews do not offer an evidence-based synthesis for focused questions, nor do they offer definitive guideline statements. All types of narrative reviews offer interpretations that are open to critique and will vary depending on the author team or context of the review.

Conclusions

Well-done narrative reviews provide a readable, thoughtful, and practical synthesis on a topic. They allow review authors to advance new ideas while describing and interpreting literature in the field. Narrative reviews do not aim to be systematic syntheses that answer a specific, highly focused question; instead, they offer carefully thought out and rigorous interpretations of a body of knowledge. Such reviews will not provide an exhaustive, comprehensive review of the literature; however, they are useful for a rich and meaningful summary of a topic.

Composing an Authentic, Academic Narrative Literature Review: How to Evaluate Scholarly Articles and Write a Thorough Narrative Literature Review

Over the course of many years of teaching, I’ve found that both my students and I struggle with our course unit on research writing. It’s boring, it’s difficult, and we all undoubtedly become aggravated with each other throughout the process.

If you’ve ever experienced a lesson burnout, like I have so many times, you know how frustrating it can be for both teacher and students. Unless you’ve written tons of research papers in your lifetime, they can seem like a daunting task. This is especially true for middle school and high school students who are likely just learning how to do so.

If your students are embarking on a research project, one of their first steps in the research process will be completing a comprehensive narrative literature review.

Ironically, I’ve had to do my own narrative literature review of sorts to bring you the resources you’ll find herein. Of note, after you’ve made it to the end of this post, you’ll be able to effectively guide your students in composing a narrative literature review by focusing on these basic tenets:

What is a narrative literature review?

• Systematic vs. Narrative literature reviews.
• The different types of narrative literature reviews.
• Steps in writing a narrative literature review.

Defining, Differentiating, and Composing a Narrative Literature Review

Essentially, it is a step in the research process that follows selecting a topic and asking a research question. Before developing an engaging thesis, a researcher has to ascertain that scholarly literature exists in support of their proposed thesis.

For students who have grown up with the ability to simply Google a wealth of information and receive desired results in a moment’s time, vetting sources may seem like a foreign concept. Teaching your students how to write this type of work will teach them how to scrutinize sources.

But what is a narrative literature review? According to top researchers, “A literature review is a type of research article published in a professional peer-reviewed journal.” These articles are published in vetted, scholarly journals that you and your students can trust as fact.

In essence, your students select a research topic then hit the databases in search of reputable, trustworthy journal articles that answer their research query and support their anticipated position on that topic. By reviewing the existing literature on the selected topic, students can be sure there is proven data and a body of existing knowledge that supports their thesis.

According to J.D. Baker, a professor at Charles Sturt University, acquiring current and relevant literature on a given topic is, “…an essential part of the research process [that] help[s] to establish a theoretical framework and focus or context for your research.” For this reason, the narrative literature review may very well be one of the most important steps in the research process.

As one of the first few steps in the research process, a step that is likely a foreign task to your students, it’s imperative that the process is broken down into simplified, manageable tasks.

Rebecca Alber, blogger for Edutopia, discusses the importance of scaffolding projects for students. She expounds upon the pedagogy of breaking projects into manageable chunks and “providing concrete structure for each.”

By reading through and analyzing the body of knowledge on a given topic, researchers, like your students, can focus and justify their research. As discussed here , the thesis is the most important part of a research paper, but you can’t arrive at your thesis without a thorough narrative literature review.

In this video, research specialist, Sarah Bronson, explains what a narrative literature review does, how to plan it, and how to write a cohesive and proper review.

Systematic vs. Narrative Literature Reviews: Knowing the Difference

In short, the difference between a narrative literature review and a systematic literature review has to do with the search terms used and the methodology employed when searching databases.

According to those in the know, “A narrative literature review is fairly broad, as it involves gathering, critiquing and summarizing journal articles and textbooks about a particular topic.” In other words, you enter general search terms into a search engine and sift through the yielded articles.

Essentially, a narrative literature review summarizes and synthesizes the body of work on a topic. The review may be generally focused on a broad topic or a specific research question.

A systematic literature review, on the other hand, “tend[s] to use specific search terms and inclusion/exclusion criteria, whereas the criteria for narrative reviews may not be as strict.” This type of work is best employed by writers who have already focused their query and/or thesis. By including or excluding particular terms, a more pointed search return is gleaned.

In essence, the goal of a systematic literature review is to answer a focused objective question. To be clear, in this type of work, the researcher is working with a clearly defined question.

Check out this helpful video that further explicates the point and process of a systematic literature review. Cochrane provides insight into why, in some instances, a systematic review is more useful than its narrative counterpart.

Though both systematic and narrative literature reviews can be useful in producing desired and relevant research documents, knowing which method to use depends on your experience and how far into the research process you’ve gone.

If you are beginning preliminary research, you’ll likely only be able to perform a narrative literature review. You may have a general topic that you’d like to investigate before committing to a topic and a thesis.

However, if you’ve already focused your study and have a better grip on the direction you wish to go, then you may find the systematic review to be useful.

Again, the literature review is just one step in a series of interrelated steps that help students write a focused and cohesive research paper. In this article, you can take a look at later steps in the writing process.

Narrative Literature Reviews: Four Unique Approaches

According to Onwuegbuzie and Frels, there are four common types of narrative literature reviews. Essentially, literature reviews can be broken down into these four categories: general, methodological, theoretical, and historical. Let’s take a look at how they differ from one another.

A general literature review takes a close look at the most important and most current knowledge on a given topic. This type of work will form the basis for your thesis or dissertation; it’s what you’ll do before focusing your query.

Sources cited in a general literature review may include scholarly articles, governmental data, books, interviews, and websites. The general literature includes a summary and assessment of the literature.

A methodological literature review defines the methodology used to apprehend the literature. In other words, this type of paper outlines and explains research methods and parameters.

The methodological literature review analyzes how information was arrived at not necessarily what the literature asserts.

A theoretical literature review analyzes how theories inform research practices. Basically, this type of paper identifies pre-existing theories, the connection between and among them, how well scrutinized the theories are, and the development of new possible theories.

Finally, a historical literature review focuses on the emergence, development, and historical context of a research topic as it presents in a body of knowledge. To be clear, this type of literature review traces the history of a particular issue or theory and how it has evolved since its onset.

In this excellent resource featuring Leigh Hall of teachingacademia.com, Hall further explains the different types of narrative literature reviews. Hall explains the four types of reviews in further detail to help writers determine which is best suited for their research purposes.

Teachers should be clear about their expectations of students concerning which type of narrative literature review is expected of them. A closer look at which type of review is best suited to your students’ projects can help you, the teacher, in guiding your students.

As one of the most important steps in the research process, it’s imperative students can successfully complete a literature review before moving on in the research process.

Lisa L. Munro, Phd., a blogger who examines the importance of creating writing communities among our students, asserts the importance of, “writing a concise literature review just comprehensive enough for the purpose of an academic journal article.”

Narrative Literature Review: A Writer’s Checklist

The writing process is a step-by-step undertaking and some steps are more of a process than others. That’s especially true of composing a narrative literature review.

Essentially, a narrative literature review is a project in and of itself. A proper review adheres to the following steps.

Entitle your review as a “review of…” Titling your work this way lets your reader know exactly what you’re setting out to do in the subsequent paragraphs. However, as a researcher, doing so helps you keep your sources organized and makes it easy to refer back to that source.

Write a brief summary of the article and how it applies to your course of study. This step is where you synthesize the information gleaned from a particular source. It will provide you, the researcher, with an opportunity to decide if it’s useful information that will support your research query.

Your abstract should include a sentence about how the source applies to your own research, your purported thesis, a summary of the literature, and conclusions you’ve made based on your findings.

Introduction

The writer provides his/her rationale and objectives for the literature review. Your introduction should establish your topic of study and an explanation of why your research is important.

Describe the methods used in performing the research. Essentially this is a few sentences explaining the steps and mediums used to acquire your sources. This indicates whether or not your research comes from reputable sources.

Here is where you explain if you used computer databases along with the search terms you employed, scoured physical files at a given office building, read physical texts on a given topic, etc.

Discussion/Summary

The writer discusses his/her discoveries as well as an overall summary of the information. Without repeating what you’ve written in the other parts of your review, in the discussion, you summarize your main findings, interpret those findings, identify the strengths and weaknesses of the given source, compare your findings with other literature on the topic, explain how and if your findings answer your research query, and assert if your thesis is supported by the literature.

In this helpful tutorial, David Taylor, an online writing professor, walks you through the formatting of a literature review. He walks writers through the five-step process of completing a paper in less than 30 minutes.

As in writing any type of composition, students should be reminded to carefully proofread for clarity and correctness. I always suggest that students read their compositions aloud as readers will often hear mistakes before they see them.

A final consideration that students inevitably need to be reminded of is avoiding plagiarism. I find it’s helpful to define plagiarism for students so there’s no question about why copying another’s ideas is problematic.

There are many online plagiarism checkers for teachers and students to use to ensure work is entirely authentic. Check out this article for some tips and tricks for avoiding and identifying plagiarism.

One of the most arduous tasks in a research project is gathering the right sources for your purpose. Help students understand how to search in the right places for articles and how to evaluate sources.

One of the questions my students rightfully ask is why they can’t use news media websites. News networks like CNN deliver the facts, don’t they? This article may help you and them to better recognize and evaluate credible source material.

A thorough narrative literature review will get your students off on the right foot. Everything after the literature review falls into place more readily when you have the right sources for your purpose.

Narrative or traditional literature reviews can take many shapes and forms. They do not need to follow any specific guideline or standard. A narrative literature view may be assigned as part of your coursework or capstone.

A narrative literature review can be a first step to building on other research in the field. After all, if it's a topic that you're interested in, you need to know what's already been done, right?

Your Narrative Literature Review Should Have...

• A clearly defined topic
• A search for relevant literature
• A logical organization structure
• An interpretation and discussion of the selected relevant literature

A common structure for narrative literature reviews is IMRaD, or:

• Introduction
• What is your topic?
• What are you interested in finding out?
• Why did you select this topic?
• How did you look for the literature?
• Where did you look?
• What search terms did you use?
• What kind of literature did you find?
• Did the literature you found change your opinion on the topic?
• Did you find out something new?
• What were the key concepts?
• and Discussion
• Evaluate and summarize the major concepts
• Connect the major concepts to future research potential

While the structure above may be sufficient for your topic, you may also consider using the similar but more robust structure IAMRDC, or:

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

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 .

A narrative literature review is an integrated analysis of the existing literature used to summarize a body of literature, draw conclusions about a topic, and identify research gaps.  By understanding the current state of the literature, you can show how new research fits into the larger research landscape.  

A narrative literature review is NOT:  

• Just a summary of sources
• A review of  everything  written on a particular topic
• A research paper arguing for a specific viewpoint - a lit review should avoid bias and highlight areas of disagreements
• A systematic review

Purposes of a narrative literature review:

• Explain the background of research on a topic
• Demonstrate the importance of a topic
• Suggest new areas of research
• Identify major themes, concepts, and researchers in a topic
• Identify critical gaps, points of disagreement, or flawed approaches for a research topic

1. Choose a topic & create a research question

• Use a narrow research question for more focused search results
• Use a question framework such as PICO to develop your research question
• Breakdown your research question into searchable concepts and keywords
• Research skills tutorials : How to choose a topic
• Ask a librarian for assistance

2. Select the sources for searching & develop a search strategy

• Identify databases to search for articles relevant to your topic
• Ask a librarian for recommended databases
• Develop a comprehensive search strategy using keywords, controlled vocabularies and Boolean operators
• Research skills tutorials: How to develop a search strategy

3. Conduct the search

• Use a consistent search strategy between databases
• Document the strategies employed to keep track of which are more successful
• Use a citation manager to organize your search results
• Ask a librarian for help or refer to the Research skills tutorials

4. Review the references

• Review the search results for relevant articles that answer your research question
• Review the bibliography of all relevant articles for additional sources
• Consider developing subfolders in the citation manager to organize sources by topic
• Use interlibrary loan for any articles without full text access

5. Summarize findings

• Synthesize the findings from the articles into a final paper
• The final paper should cover the themes identified in the research, explain any conflicts or disagreements, identify research gaps and potential future research areas, explain how this narrative review fits within the existing research and answer the research question .

Literature Review: Traditional or narrative literature reviews

Traditional or narrative literature reviews.

• Scoping Reviews
• Systematic literature reviews
• Annotated bibliography
• Keeping up to date with literature
• Finding a thesis
• Evaluating sources and critical appraisal of literature
• Managing and analysing your literature
• Further reading and resources

A narrative or traditional literature review is a comprehensive, critical and objective analysis of the current knowledge on a topic. They are an essential part of the research process and help to establish a theoretical framework and focus or context for your research. A literature review will help you to identify patterns and trends in the literature so that you can identify gaps or inconsistencies in a body of knowledge. This should lead you to a sufficiently focused research question that justifies your research.

Onwuegbuzie and Frels (pp 24-25, 2016) define four common types of narrative reviews:

• General literature review that provides a review of the most important and critical aspects of the current knowledge of the topic. This general literature review forms the introduction to a thesis or dissertation and must be defined by the research objective, underlying hypothesis or problem or the reviewer's argumentative thesis.
• Theoretical literature review which examines how theory shapes or frames research
• Methodological literature review where the research methods and design are described. These methodological reviews outline the strengths and weaknesses of the methods used and provide future direction
• Historical literature review which focus on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.

How To Structure Your Literature Review

3 options to help structure your chapter.

By: Amy Rommelspacher (PhD) | Reviewer: Dr Eunice Rautenbach | November 2020 (Updated May 2023)

Writing the literature review chapter can seem pretty daunting when you’re piecing together your dissertation or thesis. As  we’ve discussed before , a good literature review needs to achieve a few very important objectives – it should:

• Demonstrate your knowledge of the research topic
• Identify the gaps in the literature and show how your research links to these
• Provide the foundation for your conceptual framework (if you have one)
• Inform your own  methodology and research design

To achieve this, your literature review needs a well-thought-out structure . Get the structure of your literature review chapter wrong and you’ll struggle to achieve these objectives. Don’t worry though – in this post, we’ll look at how to structure your literature review for maximum impact (and marks!).

But wait – is this the right time?

Deciding on the structure of your literature review should come towards the end of the literature review process – after you have collected and digested the literature, but before you start writing the chapter. 

In other words, you need to first develop a rich understanding of the literature before you even attempt to map out a structure. There’s no use trying to develop a structure before you’ve fully wrapped your head around the existing research.

Equally importantly, you need to have a structure in place before you start writing , or your literature review will most likely end up a rambling, disjointed mess. 

Importantly, don’t feel that once you’ve defined a structure you can’t iterate on it. It’s perfectly natural to adjust as you engage in the writing process. As we’ve discussed before , writing is a way of developing your thinking, so it’s quite common for your thinking to change – and therefore, for your chapter structure to change – as you write. 

Need a helping hand?

Like any other chapter in your thesis or dissertation, your literature review needs to have a clear, logical structure. At a minimum, it should have three essential components – an  introduction , a  body   and a  conclusion . 

Let’s take a closer look at each of these.

1: The Introduction Section

Just like any good introduction, the introduction section of your literature review should introduce the purpose and layout (organisation) of the chapter. In other words, your introduction needs to give the reader a taste of what’s to come, and how you’re going to lay that out. Essentially, you should provide the reader with a high-level roadmap of your chapter to give them a taste of the journey that lies ahead.

Here’s an example of the layout visualised in a literature review introduction:

Your introduction should also outline your topic (including any tricky terminology or jargon) and provide an explanation of the scope of your literature review – in other words, what you  will   and  won’t   be covering (the delimitations ). This helps ringfence your review and achieve a clear focus . The clearer and narrower your focus, the deeper you can dive into the topic (which is typically where the magic lies). 

Depending on the nature of your project, you could also present your stance or point of view at this stage. In other words, after grappling with the literature you’ll have an opinion about what the trends and concerns are in the field as well as what’s lacking. The introduction section can then present these ideas so that it is clear to examiners that you’re aware of how your research connects with existing knowledge .

2: The Body Section

The body of your literature review is the centre of your work. This is where you’ll present, analyse, evaluate and synthesise the existing research. In other words, this is where you’re going to earn (or lose) the most marks. Therefore, it’s important to carefully think about how you will organise your discussion to present it in a clear way. 

The body of your literature review should do just as the description of this chapter suggests. It should “review” the literature – in other words, identify, analyse, and synthesise it. So, when thinking about structuring your literature review, you need to think about which structural approach will provide the best “review” for your specific type of research and objectives (we’ll get to this shortly).

There are (broadly speaking)  three options  for organising your literature review.

Option 1: Chronological (according to date)

Organising the literature chronologically is one of the simplest ways to structure your literature review. You start with what was published first and work your way through the literature until you reach the work published most recently. Pretty straightforward.

The benefit of this option is that it makes it easy to discuss the developments and debates in the field as they emerged over time. Organising your literature chronologically also allows you to highlight how specific articles or pieces of work might have changed the course of the field – in other words, which research has had the most impact . Therefore, this approach is very useful when your research is aimed at understanding how the topic has unfolded over time and is often used by scholars in the field of history. That said, this approach can be utilised by anyone that wants to explore change over time .

For example , if a student of politics is investigating how the understanding of democracy has evolved over time, they could use the chronological approach to provide a narrative that demonstrates how this understanding has changed through the ages.

Here are some questions you can ask yourself to help you structure your literature review chronologically.

• What is the earliest literature published relating to this topic?
• How has the field changed over time? Why?
• What are the most recent discoveries/theories?

In some ways, chronology plays a part whichever way you decide to structure your literature review, because you will always, to a certain extent, be analysing how the literature has developed. However, with the chronological approach, the emphasis is very firmly on how the discussion has evolved over time , as opposed to how all the literature links together (which we’ll discuss next ).

Option 2: Thematic (grouped by theme)

The thematic approach to structuring a literature review means organising your literature by theme or category – for example, by independent variables (i.e. factors that have an impact on a specific outcome).

As you’ve been collecting and synthesising literature , you’ll likely have started seeing some themes or patterns emerging. You can then use these themes or patterns as a structure for your body discussion. The thematic approach is the most common approach and is useful for structuring literature reviews in most fields.

For example, if you were researching which factors contributed towards people trusting an organisation, you might find themes such as consumers’ perceptions of an organisation’s competence, benevolence and integrity. Structuring your literature review thematically would mean structuring your literature review’s body section to discuss each of these themes, one section at a time.

Here are some questions to ask yourself when structuring your literature review by themes:

• Are there any patterns that have come to light in the literature?
• What are the central themes and categories used by the researchers?
• Do I have enough evidence of these themes?

PS – you can see an example of a thematically structured literature review in our literature review sample walkthrough video here.

Option 3: Methodological

The methodological option is a way of structuring your literature review by the research methodologies used . In other words, organising your discussion based on the angle from which each piece of research was approached – for example, qualitative , quantitative or mixed  methodologies.

Structuring your literature review by methodology can be useful if you are drawing research from a variety of disciplines and are critiquing different methodologies. The point of this approach is to question  how  existing research has been conducted, as opposed to  what  the conclusions and/or findings the research were.

For example, a sociologist might centre their research around critiquing specific fieldwork practices. Their literature review will then be a summary of the fieldwork methodologies used by different studies.

Here are some questions you can ask yourself when structuring your literature review according to methodology:

• Which methodologies have been utilised in this field?
• Which methodology is the most popular (and why)?
• What are the strengths and weaknesses of the various methodologies?
• How can the existing methodologies inform my own methodology?

3: The Conclusion Section

Once you’ve completed the body section of your literature review using one of the structural approaches we discussed above, you’ll need to “wrap up” your literature review and pull all the pieces together to set the direction for the rest of your dissertation or thesis.

The conclusion is where you’ll present the key findings of your literature review. In this section, you should emphasise the research that is especially important to your research questions and highlight the gaps that exist in the literature. Based on this, you need to make it clear what you will add to the literature – in other words, justify your own research by showing how it will help fill one or more of the gaps you just identified.

Last but not least, if it’s your intention to develop a conceptual framework for your dissertation or thesis, the conclusion section is a good place to present this.

Example: Thematically Structured Review

In the video below, we unpack a literature review chapter so that you can see an example of a thematically structure review in practice.

Let’s Recap

In this article, we’ve  discussed how to structure your literature review for maximum impact. Here’s a quick recap of what  you need to keep in mind when deciding on your literature review structure:

• Just like other chapters, your literature review needs a clear introduction , body and conclusion .
• The introduction section should provide an overview of what you will discuss in your literature review.
• The body section of your literature review can be organised by chronology , theme or methodology . The right structural approach depends on what you’re trying to achieve with your research.
• The conclusion section should draw together the key findings of your literature review and link them to your research questions.

Great work. This is exactly what I was looking for and helps a lot together with your previous post on literature review. One last thing is missing: a link to a great literature chapter of an journal article (maybe with comments of the different sections in this review chapter). Do you know any great literature review chapters?

I agree with you Marin… A great piece

I agree with Marin. This would be quite helpful if you annotate a nicely structured literature from previously published research articles.

Awesome article for my research.

I thank you immensely for this wonderful guide

It is indeed thought and supportive work for the futurist researcher and students

Very educative and good time to get guide. Thank you

Great work, very insightful. Thank you.

Thanks for this wonderful presentation. My question is that do I put all the variables into a single conceptual framework or each hypothesis will have it own conceptual framework?

Thank you very much, very helpful

This is very educative and precise . Thank you very much for dropping this kind of write up .

Pheeww, so damn helpful, thank you for this informative piece.

comprehensive explanation. Help us by pasting the URL of some good “literature review” for better understanding.

great piece. thanks for the awesome explanation. it is really worth sharing. I have a little question, if anyone can help me out, which of the options in the body of literature can be best fit if you are writing an architectural thesis that deals with design?

I am doing a research on nanofluids how can l structure it?

Beautifully clear.nThank you!

Lucid! Thankyou!

Brilliant work, well understood, many thanks

I like how this was so clear with simple language 😊😊 thank you so much 😊 for these information 😊

Insightful. I was struggling to come up with a sensible literature review but this has been really helpful. Thank you!

You have given thought-provoking information about the review of the literature.

Thank you. It has made my own research better and to impart your work to students I teach

I learnt a lot from this teaching. It’s a great piece.

I am doing research on EFL teacher motivation for his/her job. How Can I structure it? Is there any detailed template, additional to this?

You are so cool! I do not think I’ve read through something like this before. So nice to find somebody with some genuine thoughts on this issue. Seriously.. thank you for starting this up. This site is one thing that is required on the internet, someone with a little originality!

I’m asked to do conceptual, theoretical and empirical literature, and i just don’t know how to structure it
