Effective note-taking is a valuable skill for reciting and recalling information. Librarians often see students in a panic because they didn't record information about a source and can't find the source again. Save yourself time, effort and frustration: Keep good notes on your sources. The information you need for a bibliographic citation (regardless of the citation style you're using) depends on the type of source you're using.
When we say do your paper in "APA" we mean do your paper according to the guidelines in the Publication Manual of the American Psychological Association, 6th edition.
APA style is used by researchers and professionals to format papers,
cite sources in-text, and list references at the end of their papers.
