Annotated Bibliographies

What Is an Annotated Bibliography?

An annotated bibliography is a list of citations to books, articles, and documents. An annotation is an additional comment in which you describe the nature and value of each cited source. The annotation provides the reader with essential critical information and a foundation for further research. Each citation is followed by a brief (usually about 150 words) descriptive and evaluative paragraph, the annotation. The purpose of the annotation is to inform the reader of the relevance, accuracy, and quality of the sources cited.

Each entry in an annotated bibliography includes:

  • The full citation for the source, following style guidelines (e.g. APA or MLA style)
  • The annotation of the source, which can be as short as a couple of sentences or as long as multiple pages. Generally, annotations are brief and are no longer than a paragraph.

Annotations should summarize the source in the context of the topic of the annotated bibliography as a whole. The annotation is not intended to be a full summary, but rather a brief explanation of how the source is relevant to the topic and includes a critical analysis of the source.

Annotations vs. Abstracts

Abstracts are the purely descriptive summaries often found at the beginning of scholarly journal articles or in periodical indexes. Annotations are descriptive and critical; they may describe the author's point of view, authority, or clarity and appropriateness of expression.

The Process

Creating an annotated bibliography calls for the application of a variety of intellectual skills: concise exposition, succinct analysis, and informed library research.

First, locate and record citations to books, periodicals, and documents that may contain useful information and ideas on your topic. Briefly examine and review the actual items. Then choose those works that provide a variety of perspectives on your topic.

Cite the book, article, or document using the appropriate style.

Write a concise annotation that summarizes the central theme and scope of the book or article. Include one or more sentences that (a) evaluate the authority or background of the author, (b) comment on the intended audience, (c) compare or contrast this work with another you have cited, or (d) explain how this work illuminates your bibliography topic.

How Do I Make an Annotated Bibliography?

Consider the scope of your annotated bibliography. Does it have to be comprehensive? Did your instructor specify how many sources should be included?

Do a search of the literature. Check the library databases for scholarly articles, books, and other materials on your topic. Look at the citations at the end of the scholarly resources you find to find related resources. Are there titles that appear regularly? Try to find copies of those works, as they may be important in the field of inquiry.

Evaluate your sources. Read and take notes. Jot down basic impressions about the source and its relevance to your topic.

From your selected sources, create a bibliography in your chosen style (ie. ASA, MLA, APA, Chicago, etc.). The Library has style guides that can help you create an accurate bibliography.

Annotations should briefly:

  • Explain the purpose, scope and significance of the source.
  • Address the theoretical basis of the work.
  • Describe the currency of the source, and how that effects the relevancy of it.
  • Consider the biases of the source.
  • Mention features such as indices, glossaries, appendices, etc.

Sample Annotated Bibliography Entries

APA Style 

(Publication Manual of the American Psychological Association, 7th edition, 2019)

Waite, L., Goldschneider, F., & Witsberger, C. (1986). Nonfamily living and the erosion of traditional family orientations among young adults. American Sociological Review, 51(4), 541-554.

The authors, researchers at the Rand Corporation and Brown University, use data from the National Longitudinal Surveys of Young Women and Young Men to test their hypothesis that nonfamily living by young adults alters their attitudes, values, plans, and expectations, moving them away from their belief in traditional sex roles. They find their hypothesis strongly supported in young females, while the effects were fewer in studies of young males. Increasing the time away from parents before marrying increased individualism, self-sufficiency, and changes in attitudes about families. In contrast, an earlier study by Williams cited below shows no significant gender differences in sex role attitudes as a result of nonfamily living.
