Ordering works on the APA reference page
An APA Style reference page is ordered alphabetically by the first element in the reference entry, usually the first author’s last name.
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
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.
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.
Different authors with the same last name
Order works from different authors with the same last name based on their initials.
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.
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.
Nothing precedes something
Shorter names precede longer names with which they share all their letters.
Apostrophes, hyphens, parentheses, and brackets
Disregard apostrophes and hyphens in two-word names, and disregard anything in parentheses (e.g., contributor roles) or brackets (e.g., usernames).
M’, Mc, and Mac
Order prefixes such as M’, Mc, and Mac as spelled, not as sounded out.
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.

- Is there a tool that can order my references automatically?
Popular word processors like Microsoft Word and Google Docs can order lists in alphabetical order, but they don’t follow the APA Style alphabetization guidelines.
If you use Scribbr’s APA Citation Generator to create citations, references are ordered automatically based on the APA guidelines, taking into account all the exceptions.
