AMA Style is the citation and research paper format of the American Medical Association. It is often used in medical, health, or biological sciences publishing.
The Bluebook style guide prescribes the most widely used legal citation system in the United States. The Bluebook is compiled by the Harvard Law Review Association, the Columbia Law Review, the University of Pennsylvania Law Review, and the Yale Law Journal. It is used by most law schools and paralegal programs.
This style is used by the humanities and social sciences disciplines. There are a few minor differences between Turabian's A Manual for Writers and The Chicago Manual of Style. While The Chicago Manual of Style focuses on providing guidelines for publishing, Turabian's A Manual for Writers is intended for the creation and submission of academic research papers, theses, and dissertations. Turabian's manual is designed to "better suit the requirements of academic papers as opposed to published works."
