AMA Manual of Style (10th ed., 2007)

The AMA Manual of Style provides guidelines for all aspects of manuscript preparation, including grammar and punctuation.  Section 1, chapter 3, References, contains complete information about how to cite information sources in your paper.  Some examples of commonly used references include

  • Book—single author (see chapter 1, sections 3.12.1-11 for complete book citation information)
    Shepard TH. Catalog of Teratogenic Agents. 7th ed. Baltimore, MD: Johns Hopkins Press; 1992.
  • Book—multiple authors (list all authors if six or fewer, otherwise list first three followed by "et al.")
    Baselt RC, Cravey RH. Disposition of Toxic Drugs and Chemicals in Man. 4th ed. Foster City, CA: Chemical Toxicology Institute; 1995.
  • Book—with editors

    Simon JA, Hudes ES. Relationship of Ascorbic Acid to Blood Lead Levels. JAMA. 1999;281(24):2289-2293. doi:10.1001/jama.281.24.2289.

  • Online website
    King MW. The Medical Biochemistry Page. Updated July 14, 2009. Accessed July 14, 2009.
  • Interpersonal communication
    The AMA Style Guide requires that personal communications such as conversations, emails and listserv messages, and unpublished interviews be cited parenthetically within the text, rather than in the reference list at the end of the manuscript.  See chapter 1, section 3.13.9 for more information.

Most important things to remember

  • Use superscript Arabic numbers within the text to cite information (e.g.,1, 2, 3…).
  • Place the corresponding references in a numbered list at the end of your paper.  The references are listed in the order they were cited in the paper, not alphabetically by author's last name.
  • The format for author names is "Surname1 AB, Surname2 CD,...".  Note that there is a comma between each full name, but there is no punctuation within each name. 
  • If a reference has up to six authors, include them all.  If there are more than six authors, list the first three, followed by "et al."

Journal abbreviations

AMA style requires that you use abbreviated journal titles.  Journal abbreviations can be found through the NLM Catalog of Journals Referenced in the NCBI Databases.  Type the full journal name into the search box, then look for the NLM Title Abbreviation for that journal.
