Using APA style for referencing (an author/date system) Citing references in the body of a paper: If the reference has 1-2 authors: Use the one or both authors every time, with date: Pate (1995) OR (Pate, 1995) Smith and Jones (1999) OR (Smith and Jones, 1999) If the reference has 3-5 authors: Use all names the first time you cite it in the paper: Smith, Jones, Green, and Black (2001) OR (Smith, Jones, Green, and Black, 2001) Every time after that use the shortened form with "et al.": Smith et al. (2001) OR (Smith et al., 2001) If the reference has 6 or more authors: Use the shortened form every time: Jones et al. (2002) OR (Jones et al., 2002) Within a paragraph in which you cite the same reference several times, you only need to give the date once, unless readers could get confused.
