how the source might fight into an argument.

An annotated bibliography is like an expanded Works Cited (MLA) or References (APA) page where your reader sees not only the formal citation but a paragraph containing a summary and explanation of each source. You’ll list your sources alphabetically according to MLA or APA citation style as you would in a Works Cited or References page. Each formal citation will be followed by a short paragraph containing description and summary, an indication of the credibility, authority, or bias of the source, and a statement of how the source might fight into an argument.
