How to Cite using AMA

  • Printable AMA Citation Style  (PDF format) 

    This guide provides examples of the AMA style as found in the American Medical Association manual of style, 9th edition.  (REF Closed R119.A533 1998). 

    Works Cited Listing

    AMA style requires that works cited should appear in a consecutively numbered list at the end of your research paper or report, using Arabic numerals. The numbers should coincide with the order in which the references appear in the text. Single spacing is preferred.

    In-text Parenthetical Citations

    AMA Style is very restrictive in the use of references given within the text.  Parenthetical citation of sources which meet the criteria for inclusion in a reference list should be used only in news columns and obituaries, which do not require reference lists. Please note that authors are not named, the title of the article is not given, inclusive page numbers are given.  If the journal title is abbreviated it should always be enclosed in parentheses.  If it is not abbreviated, it does not have to be in parentheses.

    (Am J Psychiatry.  1995;152:626-628).

    … as reported in the American Journal of Psychiatry (1995;152:626-628).

    E-mail should always be included parenthetically in the text.  Three elements must be included:

    1.  name of person sending the message
    2.  sender’s e-mail address
    3.  date message was sent

    Please send your submissions to mczimmerman@crabedit.mla for the winter issue of the newsletter (M.C. Zimmerman, [], e-mail, November 5, 2003).

    Personal communications are another form of information not suitable for inclusion in a reference list, and which therefore must be cited parenthetically:

     In a conversation with Dr. Shields (September 2003) …

     Dr. Dadson personally thanked Mrs. Hedreen for teaching his agriculture class (written communication, September 2003).

     For additional assistance please consult a Reference Librarian.
