English 102: College Writing (Prof. Ivanova): Annotated Bibliographies

What's an Annotated Bibliography?

The most common type of bibliography is the list of sources located at the end of a research paper, an article, or a book. The bibliographic citation entries include basic publication information about each source, such as author, title, publisher, date and page numbers. The purpose of such a bibliography is to let the reader know which sources were used to write the paper, article or book, and to help the reader locate those original sources, if desired. This type of bibliography also goes by other names, such as Works Consulted or Works Cited, depending on the citation style being used.

An annotated bibliography is more substantive. It includes not only citations for the sources used, but a short annotation of each source. This provides the reader with additional information about each source. The content of an annotation varies. It might summarize, evaluate, and/or critique a source, among other things. The length of an annotation also varies, but is generally just a few sentences or a paragraph. The citation style used to create the annotated bibliography (APA, MLA, Turabian, etc.) is up to your professor.

The following web sites may be of assistance to you when creating your annotated bibliography. These sites are provided for general assistance only. Because the format, content and length of annotations vary, please ask your professor for guidelines to follow when beginning your assignment.
