General Formatting

General Formatting

  • List all references in numerical order at the end of a paper. 
  • Make sure the reference section is single-spaced within each listing and double-spaced between each listing.
  • Include all authors up to six authors. After the third author, include "et al".
  • List the authors' names in the order that they appear in the published source. This order is determined by their role in the research described in the article. Do not list the names alphabetically.
  • List the author’s name, using the last name first, followed by the first and middle initials. There is no comma after the last name and no commas, spaces, or periods between first and middle initials.
  • Capitalize only the first word and proper nouns, the title of an article should be in all lowercase letters.
  • Abbreviate periodical titles according to the US National Library of Medicine's catalog found at .; if a title does not appear on these lists, abbreviate it according to the Construction of the National Library of Medicine Title Abbreviations Fact Sheet
  • Write one-word journal titles in full. Examples: Pediatrics, Cancer, Diabetes.
  • Italicize and capitalize periodical and book titles.


Other Important Guidelines:

  • For periodicals, there is no space between the year, the volume, or the page numbers.
  • Page numbers are always written as "257-259" not "257-59."
  • Website materials that are only online (i.e. not an online version of a journal or other print publication) should include author or organization, the title of the page, the URL, and the access date. The title should not be italicized.
  • Publication and update dates and access dates for Internet sites cited must be included. For example, Smith J. Risk Factors for Cancer. Cancer Risk Factors Web site. Published December 1, 2000. Updated January 15, 2008. Accessed February 1, 2008.
  • When a DOI is provided, use the DOI rather than the URL to cite. The DOI goes immediately after "doi:" and the accessed date is not required.
