Annotated bibliography

bibliography is a list of sources (books, journals, websites, 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:

  • Summarize: Some annotations merely summarize the source. What are the main arguments? What is the point of this book or article? What topics are covered? If someone asked what this article/book is about, what would you say? The length of your annotations will determine how detailed your summary is.

    For more help, see our handout on paraphrasing sources.

  • Assess: After summarizing a source, it may be helpful to evaluate it. Is it a useful source? How does it compare with other sources in your bibliography? Is the information reliable? Is this source biased or objective? What is the goal of this source?

    For more help, see our handouts on evaluating resources.

  • Reflect: Once you've summarized and assessed a source, you need to ask how it fits into your research. Was this source helpful to you? How does it help you shape your argument? How can you use this source in your research project? Has it changed how you think about your topic?

    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.

Abstracts are descriptive summaries that present the main points or focus of specific works (e.g., articles, books, conference proceedings). They normally do not include a critique or evaluation of the work. Abstracts usually appear at the beginning of scholarly journal articles and in the library databases (e.g., article search results list and database article records). An abstract's purpose is to help you decide whether an article is relevant to your research. 

Annotations also cover specific works (e.g., articles, books, conference proceedings) but they can include descriptive summaries, evaluative summaries, or a combination of both. A descriptive annotation summarizes the scope and content of a work whereas an evaluative annotation provides critical comment. Annotations usually appear in an annotated bibliography. Many instructors will include both an annotated bibliography as well as a research paper as part of a course's required assignments. You will typically complete an annotated bibliography assignment before you begin work on a research paper. Completing an annotated bibliography first will help you organize and write your research paper.

MLA Style - Print Book:

Ontiveros, Randy J. In the Spirit of a New People: The Cultural Politics of the Chicano Movement. New York UP, 2014. This book

analyzes the journalism, visual arts, theater, and novels of the Chicano movement from 1960 to the present as articulations of

personal and collective values. Chapter 3 grounds the theater of El Teatro Campesino in the labor and immigrant organizing of

the period, while Chapter 4 situates Sandra Cisneros’s novel Caramelo in the struggles of Chicana feminists to be heard in the

traditional and nationalist elements of the Chicano movement. Ontiveros provides a powerful and illuminating historical context

for the literary and political texts of the movement.

MLA Style - Journal Article from a Library Database:

Alvarez, Nadia, and Jack Mearns. “The benefits of writing and performing in the spoken word poetry community.” The Arts in

Psychotherapy, vol. 41, no. 3, July 2014, pp. 263-268. ScienceDirect, doi:10.1016/j.aip.2014.03.004. Spoken word poetry is

distinctive because it is written to be performed out loud, in person, by the poet. The ten poets interviewed by these authors

describe “a reciprocal relationship between the audience and the poet” created by that practice of performance. To build

community, spoken word poets keep metaphor and diction relatively simple and accessible. Richness is instead built through

fragmented stories that coalesce into emotional narratives about personal and community concerns. This understanding of

poets’ intentions illuminates their recorded performances.
