Cite all sources quoted or paraphrased in a research paper. For rules and examples of APA Style, consult the Publication Manual of the American Psychological Association, 7th ed. 2020 (copy available at Andersen Library's Reference Desk).
Online citation formatters and citation help from library databases are not foolproof. Always review your citations to be sure they are correct.
Essentially, an annotated bibliography is a bibliography (list of sources consulted) with annotations (summaries, possibly also providing evaluation of each source). Sounds simple enough, right?
There's a booklet about it at Andersen Library's Reference Desk: On compiling an annotated bibliography. 2000. Call number: Z1001 .H33 2000
There's more information about annotated bibliographies online from Purdue University's OWL (Online Writing Lab), including some examples (use the links for samples at the left side of the display).
