Planned service outage for Holland/Terrell Libraries: Wednesday, September 17th, from approximately 4:00 am to 6:00 am

ITS is performing systems/network maintenance and the following services will be unavailable during that time: Phone service, WiFi, and all WSU Pullman Libraries websites. Additionally, Search It functionality will be limited during that time.

We anticipate these services will return to full functionality no later than 6:00 am.

 

  • When a work has two authors, always cite both names every time the reference occurs in text.

Example:

As Smithers and Skinner (1993) demonstrated

as has been shown (Nahasapeemapetilon & Ormand, 1989)

  • When a work has three, four, or five authors...
    • Cite all the authors the first time the reference occurs.
    • In subsequence citations, include only the surname of the first author followed by et al. (including the period)
    • Cite the year if it is the first citation of the reference within a paragraph.

Example:

Hibbert, Rivera, Monroe, Foster, Zweig, and Colossus (1994) found
[Use as first citation in the text]

Hibbert et al. (1994) found
[Use as subsequent first citation per paragraph thereafter.]

Hibbert et al. found
[Omit year from subsequent citation after first citation within a paragraph.]

  • When a work has six or more authors, cite only the surname of the first author followed by et al.

Example:

Wiggum et al. (1983) found 
[First in a paragraph citation]

Wiggum et al. also found 
[Omit the year after the first citation in the same paragraph]

  • Exceptions in Multiple Authors...
    • If two references with the same year shorten to the same form, cite the surnames of the first authors and of as many of the subsequent authors as necessary to distinguish the two references, followed by a comma and et al.

Example:

If there are two resources with the author:
Meyers, Bobbins, & Powers, 1994, and Meyers, Powers, Bobbins, & Groening, 1994
both shorten to Meyers et al., 1994
 
Bradley, Ramirez, and Soo (1994) and Bradley, Soo, et al. (1994)
