In the reference:

Retain the order of authors as listed in the article- even if it's not alphabetical

  • Two authors:
  • Three authors:
  • If you have up to 6 authors, list all of them.
  • If you have 7 or more, list the first 6, then use an ellipse (...) before listing the final author.  Example: Brown, J. S., Armstrong, L., Connick, H. L., Whedon, J., Archer, P., Smithson, K. D., ... McCrae, R. R. 

In the in-text citation:

  • Two authors: Name both authors every time you cite the work: (Armstrong & Peters, 1998)
  • Three to five authors: List all the authors the first time you cite the work: (Ackermann, Benjes-Small, Brainard, Smith, & Vassady, 2009).  After the first time, use only the first author's name followed by et al.: (Ackermann et al., 2009).
  • Six authors or more: Never use them all in the in-text citation. Instead, use the first author's name followed by et al.
  • NOTE: In et al., the al. is followed by a period- the et is not.
  • NOTE: et al. is used in the in-text citations but never in the reference list

Note that "et al" is used only in the in-text citation, never in the full reference.
