  • When the DOI is given for a journal article, AMA style prefers that the DOI is cited instead of the URL. Do not cite both.
  • Authors. For 1-6 authors include all names.  More than 6 authors, include first three names followed by ,et al.
  • Journals may not always include vol/issue/page numbering, and/or may include an article number in place of these details. Include the details you have in this area.
  • Abbreviated journal name is in italics.
  • Journal abbreviations. AMA employs journal abbreviations as set by the National Library of Medicine (NLM) Journals referenced in the NCBI Databases.
    • Alternatively:
      • Use PubMed or OVID Medline to locate the appropriate abbreviation.
      • Check the abbreviation from your reference management program.
