Citation and style manuals

List of citation styles, corresponding online and print guides, and links to sites that provide examples.

American Psychological Association (APA) style is a widely accepted style of documentation, particularly in the social sciences. APA style specifies the names and order of headings, formatting, and organization of citations and references, and the arrangement of tables, figures, footnotes, and appendices, as well as other manuscript and documentation features. APA style uses the author-date style of parenthetical referencing, with such source citations keyed to a subsequent list of "References." Also known as the Harvard Style.
