The Publication Manual of the American Psychological Association, Seventh Edition is the official source for APA Style. It is the style manual of choice for writers, researchers, editors, students, and educators in the social and behavioral sciences, natural sciences, nursing, communications, education, business, engineering, and other fields.
This seventeenth edition of The Chicago Manual of Style has been prepared with an eye toward how we find, create, and cite information that readers are as likely to access from their pockets as from a bookshelf.
