Citation styles

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.


  • Whenever you first cite a reference within the text, use the appropriate consecutive Arabic numeral superscript. Once a citation has been assigned an Arabic numeral, it keeps the same numeral whenever it appears in text again. Place the superscript outside of periods and commas but inside semicolons and colons, for example: As noted previously,2,5-7,15 AND The derived data were as follows4,5:
  • Place the superscript immediately after a clinical author’s surname, for example: Smith7 reported on the survey; Smith and Jones8 reported on the survey; Smith et al9 reported on the survey.
  • Do not place the superscript after a number or unit of measure. Instead, place the superscript immediately after a corresponding word or phrase within the sentence containing the number or measurement, for example: The smallest lesion found in the second study10 was 1 cm.


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."
