Annotated Bibliography Basics: at least six entries (sources, in APA format), all of them must be scholarly; each annotation should be as long as five to ten lines. 1. Definition A bibliography is usually thought of as an alphabetical listing of books at the end of a written work (book, book chapter, or article), to which the author referred during the research and writing process. In addition to books, bibliographies can include sources such as articles, reports, interviews, or even non-print resources like Web sites, video or audio recordings. The standard bibliography details the citation information of the consulted sources: author(s), date of publication, title, and publisher's name and location (and for articles: journal title, volume, issue and page numbers). The primary function of bibliographic citations is to assist the reader in finding the sources used in the writing of a work. To these basic citations, the annotated bibliography adds descriptive and evaluative comments (i.e., an annotation), assessing the nature and value of the cited works. The addition of commentary provides the future reader or researcher essential critical information and a foundation for further research. 2. Composition Annotations begin on the line following the citation data and may be composed with complete sentences or as verb phrases (the cited work being understood as the subject)—again at the discretion of the instructor. The annotation could include most, if not all, of the following: Explanation of the main purpose and scope of the cited work Theoretical basis and currency of the author's argument Work's intended audience Value and significance of the work as a contribution to the subject under consideration Possible shortcomings or bias in the work Your own evaluation of the work (most important) 4.
