Citation Styles: AMA Style

American Medical Association

The citation style of the American Medical Association (AMA) is used primarily in medical research.

Here, you will find basic AMA citation formats for books, print journals, online journals, and websites. For information that is more detailed and specific, feel free to consult the AMA Manual of Style.

Additional Tips and Guidelines

  • Author names should always be formatted as "Surname, Initials" with no spaces or periods separating initials
  • Capitalize every major word in the title
  • Italicize the titles of books, websites, and journals
  • Titles of individual articles are left unitalicized, with no quotation marks either
  • For periodicals, use the abbreviated title as found on the NLM Catalog of NCBI Journals
