Basic Rules 

  In-text citation End-of-paper Reference
Basic Rules
  • Superscript numbers.1

    • When citing multiple sources:
      - more than one: 1,3,5
      - three or more: 1-3

  • ​Italic numbers (2).​

    • When citing multiple sources:
      - more than one: (1, 3, 5)
      - three or more: (1-3)

  • Author name and year of publication (Finnegan et al., 2004).​

  • If you used numerical (superscript or italic) in-text citations, put your references in numerical order; If you used author-date in-text citations, order references in alphabetical order by last name of the first author.

  • Use the CASSI tool to look up journal title abbreviations.

  • Journal abbreviation and volume are italicized. Year of publication is bolded.

Examples
  • Superscript numbers

    • as shown by Brown2,

  • Italic numbers

    • as mentioned earlier (2),

    • Smith (2003)

    • Brown and Jones (2004),
