Ordering works on the APA reference page

This article reflects the 7th edition guidelines of the APA Publication Manual.

An APA Style reference page is ordered alphabetically by the first element in the reference entry, usually the first author’s last name.

  • Smith, B. H. precedes Thompson, A. G.

In more complex situations, this basic guideline may not be enough. That’s probably why you’re here, right? Luckily, APA created more detailed guidelines that are outlined in this article.

Multiple works with the same first author

Single-author works

If the works have just one author, order them based on the publication date, listing the oldest source first. Works with no date come before works with a date. Works that are “In press” come last.

  • Warren, K. J. (n.d.)
  • Warren, K. J. (2018)
  • Warren, K. J. (in press)

Multiple-author works

If the first author is the same, but subsequent authors are different, order the references based on the second author’s last name. If the second author is the same, then order on the third author, and so on. One-author works come before multiple-author works.

  • Palmer, T
  • Palmer, T., & Hunt, S.
  • Palmer, T., Hunt, S., & Robertson, H.

Different authors with the same last name

Order works from different authors with the same last name based on their initials.

  • Theel, M. precedes Theel, P. S.

No author (source title)

When the author of a work is unknown, the source title is moved to the author position. In this case, the reference is ordered based on the title. Disregard “A”, “An”, and “The” at the beginning of the title. If the title starts with a numeral, alphabetize it as though it were spelled out.

  • How social media influences mental health (ordered on the H of “How”)
  • The impact of smartphones on creativity (ordered on the I of “Impact”)
  • 10 ways to increase your productivity (ordered on the T of “Ten”)

Same author, same date

Works with the same author and date are distinguished with a lowercase letter after the publication year. This letter appears in the APA in-text citation and the reference entry. Order works by that lowercase letter.

  • Browning, H. (2020a) precedes Browning, H. (2020b)

Suffixes (Sr., Jr., I, II, III)

Works authored by people with the same first and last name, but with a suffix such as Jr., Sr. or I, II, III, are ordered chronologically, oldest first.
