Citation Format: AMA Style

Utilize these resources to learn more about popular citation styles used in the health sciences.


AMA Citation Style refers to the citation and manual of style from the American Medical Association. Use the information and examples provided on this page to properly format in-text and reference list citations. 

The Reference List

Your reference list should begin on a new page following the text of your paper. Here, you will include complete citations for the resources you've used in your writing. 
Tips for formatting your reference list:
  • Number references should be listed in the order they appear in the text. Do not alphabetize.
  • Do not indent if the citation extends to a second line.
  • Authors are listed with the last name first followed by the first and middle initials without periods. (E.g.: Skinner, BF)
  • Up to 6 author names should be listed.  Over 6 authors, list only the first 3, followed by "et al." 
  • Journal titles abbreviated according to PubMed abbreviations and italicized.
  • In journal titles, capitalize all major words.
  • For online journals, the DOI is preferred over the URL link.
  • In book titles, capitalize all major words.
  • When URLs are used, ensure that they are a direct as possible and the link still functions as close to publication as possible.


In-Text Citations

In addition to the Reference list, sources are also cited using superscript numbers.
Tips for formatting your reference list:
  • References are numbered in consecutive order in the text, tables, or figures.
  • Use superscript Arabic numerals (see example below).  The first reference used in the documents should be listed first on the reference list.
  • Where to insert superscript numbers:
    • Immediately next to the fact, idea or quotation being cited.
    • Outside periods and commas.
    • Inside colons and semi-colons
  • If a reference is used multiple times in the same paper, use the same number throughout.
  • When more than two references are cited at one give place, use hyphens to join the first and last numbers of the series; use commas without space to separate other parts of multiple citations 1,4-7,19,24.
  • You may refer to the author's name (last name only) in the text of your paper, as long as these are accompanied by a numbered citation.



Cite a Record

Items in Discovery@RML search results include buttons to Cite, Link, Email, Save. These buttons appear on the results list, and in the detailed record.

"Cite A Record" displays two options:
  •  Export a citation to EndNote, to RefWorks if you have access to these services. If you use a different citation management software, such as EasyBib, Mendeley, or Zotero, choose Export to RIS which creates a file of tagged data.
  • Copy a citation by selecting a style from the drop/down list of 10 citation styles then copying the formatted citation to your document.
►It is still your responsibility to proofread the citation for accuracy! Pay close attention to capitalization and the formatting of names and pages. The citation may indicate missing data that you need to insert to complete your citation. Copying and pasting may result in the loss of indentation or formatting.
