APA – Citing Sources

Several works with the same first author and the same date

If you want to refer to several works that have the same first author and year, you need to separate these references in the in-text citations. You then need to write out as many authors as necessary to separate the references.


  • Kapoor, Bloom, Montez, et al. (2017)
  • Kapoor, Bloom, Zucker, et al. (2017)

If only the last author separates the references, do not write et al. after:

  • Hasan, Liang, Kahn, and Jones-Miller (2015)
  • Hasan, Liang, Kahn, and Weintraub (2015)

APA Style: Citing Multiple Works With Three or More Authors and the Same Date
