A bibliography (also called References or Works Cited) is a list of sources. An annotated bibliogrpahy also begins with a citation but contains additional informaation about each source. An annotated bibliography may just summarize sources, in other words, explain the purpose/objectives and main points of a study or may go further by exploring how this study relates to others in the field (Writing Center, University of North Carolina, Chapel Hill, n.d.). More extensive annotated bibliographies are sometimes called evaluative annotated bibliographies or critical annotated bibliographies (Memorial Library, n.d.). Evaluative or critical annontations evaluate each source through judgements about quality. Aspects of evaluation may include the work's importance, the author's qualifications or bias, accuracy of information, and/or signifiant limitations (University of Washington Bothell & Cascadia College Library, n.d.)
The 7th ed. of the APA book (American Psychological Association, 2020) has information about the formating of annontated bibliographies on page 307 and a sample annotated bibliography on page 309.
