An annotated bibliography is a list of citations for various books, articles, and other sources on a topic. The annotated bibliography looks like a Reference page but includes an annotation after each source cited. An annotation is a short summary and/or critical evaluation of a source. Annotated bibliographies can be part of a larger research project, or can be a stand-alone report in itself.
The annotation is a concise and informative description that summarizes and evaluates the contents of a resource. It differs from an abstract, which just summarizes the original content. An annotation usually strikes a balance between summary and evaluation by addressing some of the following:
Types of Annotations
A summary annotation describes the source by answering the following questions: who wrote the document, what the document discusses, when and where was the document written, why was the document produced, and how was it provided to the public. The focus is on description.
An evaluative annotation includes a summary as listed above but also critically assesses the work for accuracy, relevance, and quality. Evaluative annotations can help you learn about your topic, develop a thesis statement, decide if a specific source will be useful for your assignment, and determine if there is enough valid information available to complete your project. The focus is on description and evaluation.
These samples have different strengths and weaknesses. The highlighting demonstrates which part of the annotation is summary and which part is evaluation. A librarian's evaluation of each annotation is provided.
Ehrenreich, Barbara. Nickel and Dimed: On (Not) Getting By in America. New York: Henry Holt and Company, 2011. Print.
In this book of nonfiction based on the journalist's experiential research, Ehrenreich attempts to ascertain whether it is currently possible for an individual to live on minimum wage in America. Taking jobs as a waitress, a maid in a cleaning service, and a Wal-Mart sales employee, the author summarizes and reflects on her work, her relationships with fellow workers, and her financial struggles in each situation. An experienced journalist, Ehrenreich is aware of the limitations of her experiment and the ethical implications of her experiential research tactics and reflects on these issues in the text. The author is forthcoming about her methods and supplements her experiences with scholarly research on her places of employment, the economy, and the rising cost of living in America. Ehrenreich's project is timely, descriptive, and well-researched.
Librarian's Score: A-
This annotation include both summary and evaluation. The evaluation addresses authority and accuracy, but it could be a little stronger. For example, it could answer: What audience would benefit from reading this book? What I like about this annotation is the evaluation includes both the upside and downside to Ehrenreich's approach. It speaks to her position as the author (to wit: she's experienced, but she also backs up her work with research). The summary is also very good. I get a good sense of what this is about.
Waite, Linda J., Frances Kobrin Goldscheider, and Christina Witsberger. "Nonfamily living and the erosion of traditional family orientations among young adults." American Sociological Review 51.4 (1986): 541-554. Print.
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.
Librarian's Score: C
This annotation is mostly summary. The summary is strong, but the evaluation is weak. I’m glad to learn that the authors work for reputable institutions, but more evaluation could be included.
Kotrla, Kimberly. "Domestic minor sex trafficking in the United States." Social Work 55.2 (2010): 181-187. Academic Search Premier. Web. 15 Mar 2012.
This article is about the sex trafficking of children and young adults. It is more commonly now being called "domestic minor sex trafficking." It is considered modern-day slavery. The author discusses: victims, the supply and demand of domestic minor sex tracking, how different countries tolerate it, help provided to survivors, and what this type of trafficking is. This evidence is credible because it comes from social workers who work for the government. The goals of this source is to explain to people what domestic minor sex trafficking is, who is at risk, and what social workers can do to stop this problem. It also brings up the human trafficking in the United States. The author, Kimberly Kotrla, is an assistant professor in the School of Social Work at Baylor University in Waco, Texas. She was a social worker for 10 years and does a lot of research about human trafficking. She gives most of her attention to the sexual exploitation of children in America. Kotrla is also on the human trafficking prevention task force committee. The audience of this article is most likely parents of young children and social workers. Published in 2010, it is fairly current. I felt that this source was an easy read, but written for a mature and educated audience.
Librarian's Score: B
This student did a great job of combining summary and evaluation. She told me what the article is about, its content as well as its purpose ("The goals of this source is..."). She addresses the author's credentials, the audience for the piece, and currency, and also the accuracy of the information ("social workers who work for the government"). However, this annotation lacks a critical analysis of how this article is relevant for the student's research question.
