What is an annotated bibliography?
A bibliography is a list of different sources (books, journals, Web sites, etc.) used for researching a topic. Bibliographies are sometimes called "References" or "Works Cited". An annotation is a summary and/or evaluation. It is NOT the same as the notes you would take from a source. So, an annotated bibliography is a summary and/or evaluation of each of the sources listed.
