Annotated bibliography

Writing an annotated bibliography.

purpose of annotated bibliography

An annotated bibliography is a list of information sources (e.g. journal articles or book chapters) on a particular topic with a reference accompanied by a brief commentary on each source, known as an annotation . There are two main ways to organise your information sources:

The specific elements that you need to incorporate, as well as the structures required, vary between units. This includes the number and type of sources, the referencing styles, as well as what you need to discuss in the annotation. In addition to a descriptive summary, the annotation requires critical reading, which means you analyse and evaluate the text:

It is important that you carefully check the specific requirements of your task so that you understand exactly what is required.

This resource will outline some of the basic elements of an annotated bibliography, including the purpose of an annotated bibliography and how to structure one.

The purpose of an annotated bibliography

The purpose is to:

An annotated bibliography is sometimes given as an assessment task at the beginning of a research project, or, as an assessment task in the lead up to an essay, to encourage you to survey and reflect on what has already been discovered about your topic. However, it might also be given as a stand-alone assignment to develop your research and critical thinking skills .

Structuring an annotated bibliography

An annotated bibliography is made up of two parts: a reference (in some faculties this is referred to as a citation), and an annotation.

It is important to note that what is included in the reference and annotation will vary between disciplines, so it is essential to check with your assignment instructions or lecturer as to what is expected.

Q. What is an annotated bibliography and what does it do?

What is an annotated bibliography and what does it do? Answered By: Stormye Hendrix Last Updated: Aug 16, 2021

What is an annotated bibliography.

An annotated bibliography is an well-organized list of sources (can include a variety of materials, books, documents, articles, web sites, DVDs, etc.) with a paragraph or two that describes, explains, and/or evaluates each entry in terms of quality, authority, and relevance.

What Is the Purpose of an Annotated Bibliography?

An annotated bibliography may be selective or comprehensive in its coverage. A selective annotated bibliography includes just those items that are best for the topic while a comprehensive (or exhaustive) annotated bibliography attempts to identify everything available on a subject or topic.

Annotated Bibliography

What is an annotated bibliography.

An annotated bibliography provides an overview or a brief account of the available research on a given topic. It is a list of research sources that takes the form of a citation for each source, followed by an annotation - a short paragraph sumarising and evaluating the source. An annotated bibliography may be a stand-alone assignment or a component of a larger assignment. 

Purpose of an annotated bibliography

When set as an assignment, an annotated bibliography allows you to get acquainted with the material available on a particular topic.

Depending on your specific assignment, an annotated bibliography might:

What does an annotated bibliography look like?

Each entry in an annotated biliography has two components: 

The annotation usually contains a brief summary of content and a short analysis or evaluation. Depending on your assignment you may be asked to summarise, reflect on, critique, evaluate or analyse each source. While an annotation can be as brief as one sentence, a paragraph is more usual.  An example is provided below.

As with a normal reference list or bibliography, an annotated bibliography is usually arranged alphabetically according to the author’s last name.

An annotated bibliography summary should be about 100 - 200 words per citation—check with your lecturer/tutor as this may vary between faculties and assessments. Please also check with your lecturer about the elements each annotation should include.

Steps to writing an annotated bibliography

Questions to consider when selecting sources

The sources for your annotated bibliography should be carefully selected. Start by reading abstracts or skimming to help you identify and select relevant sources. Also keep in mind that, while annotated bibliographies are often ‘stand alone’ assignments, they can also be preliminary research about a particular topic or issue, and further research or a longer literature review may follow. Try to choose sources which together will present a comprehensive review of the topic.

Keep the following questions in mind to help clarify your choices

Surveying the sources

Take notes on your selected texts as you read. Pay attention to:

Evaluate and ask questions as you read

Record evaluations in your notes and consider:

How should I write the annotations?

Contents of an annotated bibliography

An annotation may contain all or part of the following elements depending on the word limit and the content of the sources you are examining.

Sample annotation  

The citation goes first and is followed by the annotation. Make sure that you follow your faculty’s preferred citation style. The summary needs to be concise. Please note the following example is entirely fictitious.

In the sample annotation below, each element is numbered (see Key).

Definitions

A bibliography is a list of sources (books, journals, Web sites, periodicals, etc.) one has used for researching a topic. Bibliographies are sometimes called "References" or "Works Cited" depending on the style format you are using. A bibliography usually just includes the bibliographic information (i.e., the author, title, publisher, etc.).

An annotation is a summary and/or evaluation. Therefore, an annotated bibliography includes a summary and/or evaluation of each of the sources. Depending on your project or the assignment, your annotations may do one or more of the following.

For more help, see our handout on paraphrasing sources.

For more help, see our handouts on evaluating resources .

Your annotated bibliography may include some of these, all of these, or even others. If you're doing this for a class, you should get specific guidelines from your instructor.

Why should I write an annotated bibliography?

To learn about your topic : Writing an annotated bibliography is excellent preparation for a research project. Just collecting sources for a bibliography is useful, but when you have to write annotations for each source, you're forced to read each source more carefully. You begin to read more critically instead of just collecting information. At the professional level, annotated bibliographies allow you to see what has been done in the literature and where your own research or scholarship can fit. To help you formulate a thesis: Every good research paper is an argument. The purpose of research is to state and support a thesis. So, a very important part of research is developing a thesis that is debatable, interesting, and current. Writing an annotated bibliography can help you gain a good perspective on what is being said about your topic. By reading and responding to a variety of sources on a topic, you'll start to see what the issues are, what people are arguing about, and you'll then be able to develop your own point of view.

To help other researchers : Extensive and scholarly annotated bibliographies are sometimes published. They provide a comprehensive overview of everything important that has been and is being said about that topic. You may not ever get your annotated bibliography published, but as a researcher, you might want to look for one that has been published about your topic.

The format of an annotated bibliography can vary, so if you're doing one for a class, it's important to ask for specific guidelines.

The bibliographic information : Generally, though, the bibliographic information of the source (the title, author, publisher, date, etc.) is written in either MLA or APA format. For more help with formatting, see our MLA handout . For APA, go here: APA handout .

The annotations: The annotations for each source are written in paragraph form. The lengths of the annotations can vary significantly from a couple of sentences to a couple of pages. The length will depend on the purpose. If you're just writing summaries of your sources, the annotations may not be very long. However, if you are writing an extensive analysis of each source, you'll need more space.

You can focus your annotations for your own needs. A few sentences of general summary followed by several sentences of how you can fit the work into your larger paper or project can serve you well when you go to draft.

Annotated Bibliographies

What this handout is about.

This handout will explain why annotated bibliographies are useful for researchers, provide an explanation of what constitutes an annotation, describe various types of annotations and styles for writing them, and offer multiple examples of annotated bibliographies in the MLA, APA, and CBE/CSE styles of citation.

Introduction

Welcome to the wonderful world of annotated bibliographies! You’re probably already familiar with the need to provide bibliographies, reference pages, and works cited lists to credit your sources when you do a research paper. An annotated bibliography includes descriptions and explanations of your listed sources beyond the basic citation information you usually provide.

Why do an annotated bibliography?

One of the reasons behind citing sources and compiling a general bibliography is so that you can prove you have done some valid research to back up your argument and claims. Readers can refer to a citation in your bibliography and then go look up the material themselves. When inspired by your text or your argument, interested researchers can access your resources. They may wish to double check a claim or interpretation you’ve made, or they may simply wish to continue researching according to their interests. But think about it: even though a bibliography provides a list of research sources of all types that includes publishing information, how much does that really tell a researcher or reader about the sources themselves?

An annotated bibliography provides specific information about each source you have used. As a researcher, you have become an expert on your topic: you have the ability to explain the content of your sources, assess their usefulness, and share this information with others who may be less familiar with them. Think of your paper as part of a conversation with people interested in the same things you are; the annotated bibliography allows you to tell readers what to check out, what might be worth checking out in some situations, and what might not be worth spending the time on. It’s kind of like providing a list of good movies for your classmates to watch and then going over the list with them, telling them why this movie is better than that one or why one student in your class might like a particular movie better than another student would. You want to give your audience enough information to understand basically what the movies are about and to make an informed decision about where to spend their money based on their interests.

What does an annotated bibliography do?

A good annotated bibliography:

What elements might an annotation include?

The first four elements above are usually a necessary part of the annotated bibliography. Points 5 and 6 may involve a little more analysis of the source, but you may include them in other kinds of annotations besides evaluative ones. Depending on the type of annotation you use, which this handout will address in the next section, there may be additional kinds of information that you will need to include.

For more extensive research papers (probably ten pages or more), you often see resource materials grouped into sub-headed sections based on content, but this probably will not be necessary for the kinds of assignments you’ll be working on. For longer papers, ask your instructor about her preferences concerning annotated bibliographies.

Did you know that annotations have categories and styles?

Decisions, decisions.

As you go through this handout, you’ll see that, before you start, you’ll need to make several decisions about your annotations: citation format, type of annotation, and writing style for the annotation.

First of all, you’ll need to decide which kind of citation format is appropriate to the paper and its sources, for instance, MLA or APA. This may influence the format of the annotations and bibliography. Typically, bibliographies should be double-spaced and use normal margins (you may want to check with your instructor, since he may have a different style he wants you to follow).

MLA (Modern Language Association)

See the UNC Libraries citation tutorial for basic MLA bibliography formatting and rules.

APA (American Psychological Association)

See the UNC Libraries citation tutorial for basic APA bibliography formatting and rules.

CBE (Council of Biology Editors)/CSE (Council of Science Editors)

See the UNC Libraries citation tutorial for basic CBE/CSE bibliography formatting and rules.

After choosing a documentation format, you’ll choose from a variety of annotation categories presented in the following section. Each type of annotation highlights a particular approach to presenting a source to a reader. For instance, an annotation could provide a summary of the source only, or it could also provide some additional evaluation of that material.

In addition to making choices related to the content of the annotation, you’ll also need to choose a style of writing—for instance, telescopic versus paragraph form. Your writing style isn’t dictated by the content of your annotation. Writing style simply refers to the way you’ve chosen to convey written information. A discussion of writing style follows the section on annotation types.

Types of annotations

As you now know, one annotation does not fit all purposes! There are different kinds of annotations, depending on what might be most important for your reader to learn about a source. Your assignments will usually make it clear which citation format you need to use, but they may not always specify which type of annotation to employ. In that case, you’ll either need to pick your instructor’s brain a little to see what she wants or use clue words from the assignment itself to make a decision. For instance, the assignment may tell you that your annotative bibliography should give evidence proving an analytical understanding of the sources you’ve used. The word analytical clues you in to the idea that you must evaluate the sources you’re working with and provide some kind of critique.

Summary annotations

There are two kinds of summarizing annotations, informative and indicative.

Summarizing annotations in general have a couple of defining features:

Informative annotation

Informative annotations sometimes read like straight summaries of the source material, but they often spend a little more time summarizing relevant information about the author or the work itself.

Indicative annotation

Indicative annotation is the second type of summary annotation, but it does not attempt to include actual information from the argument itself. Instead, it gives general information about what kinds of questions or issues are addressed by the work. This sometimes includes the use of chapter titles.

Critical/evaluative

Evaluative annotations don’t just summarize. In addition to tackling the points addressed in summary annotations, evaluative annotations:

Combination

An annotated bibliography may combine elements of all the types. In fact, most of them fall into this category: a little summarizing and describing, a little evaluation.

Writing style

Ok, next! So what does it mean to use different writing styles as opposed to different kinds of content? Content is what belongs in the annotation, and style is the way you write it up. First, choose which content type you need to compose, and then choose the style you’re going to use to write it

This kind of annotated bibliography is a study in succinctness. It uses a minimalist treatment of both information and sentence structure, without sacrificing clarity. Warning: this kind of writing can be harder than you might think.

Don’t skimp on this kind of annotated bibliography. If your instructor has asked for paragraph form, it likely means that you’ll need to include several elements in the annotation, or that she expects a more in-depth description or evaluation, for instance. Make sure to provide a full paragraph of discussion for each work.

As you can see now, bibliographies and annotations are really a series of organized steps. They require meticulous attention, but in the end, you’ve got an entire testimony to all the research and work you’ve done. At the end of this handout you’ll find examples of informative, indicative, evaluative, combination, telescopic, and paragraph annotated bibliography entries in MLA, APA, and CBE formats. Use these examples as your guide to creating an annotated bibliography that makes you look like the expert you are!
