MLA 9 changed how you handle 3+ authors
Why MLA and APA now reach for et al. sooner, and what that means for in-text citations and works-cited entries.
If you learned citation from an older handout, the modern rule for three or more authors can feel suspiciously short. MLA 9 says to list the first author followed by et al. for a source with three or more authors. APA 7 makes a similar move in the text: for three or more authors, use the first author followed by et al. from the first citation.
This is not a shortcut students invented. It is the practical direction of the current handbooks. The MLA Style Center shows the first-author-plus-et al. pattern for three or more authors, and APA 7 made the in-text version shorter than many APA 6 habits.
One small historical note keeps the title honest: the modern MLA simplification arrived with the MLA 8 and MLA 9 way of thinking about sources, not as a random isolated trick. MLA 9 is the handbook many current students are assigned, so it is where they notice the change. If your memory is from MLA 7 or an old classroom chart, MLA 9 will feel like the moment the rule changed.
What changed
Older citation habits tried to display more names before shortening the list. That made sense in a print-first classroom where a paper might use a small number of sources and where the bibliography was usually read on paper. The problem is that modern research is crowded. Journal articles can have long author teams, edited books can have several contributors, and student papers often mix database records, reports, websites, and course materials.
The result was clutter. Long author strings made in-text citations hard to read, especially when the point of the sentence was the evidence, not the roster. A citation should identify the source quickly and point the reader to the full entry. It should not pull attention away from the argument every time a multi-author article appears.
The MLA 9 rule
In MLA 9, a works-cited entry for three or more authors begins with the first author named in the source, followed by et al. Then the rest of the entry continues as usual. The in-text citation also uses the first author.
The punctuation is small but worth getting right. Et al.is short for Latin words meaning "and others," so the period belongs after al. In an MLA works-cited entry, the comma after the first author still comes before et al. because the author element is continuing in normal MLA order.
Works cited example: Garcia, Elena, et al. "Peer Review in First-Year Writing." Journal of Writing Studies, vol. 18, no. 2, 2025, pp. 44-61.
In-text example: Garcia et al. argue that feedback works best when students revise within a week of receiving comments.
The APA 7 rule
APA changed in a slightly different place. In the reference list, APA still lists many authors before using an ellipsis in very long entries. But in the text, APA 7 uses et al. immediately for three or more authors. You do not write out all three names the first time anymore.
Reference list example: Garcia, E., Patel, M., & Chen, R. (2025). Peer review in first-year writing. Journal of Writing Studies, 18(2), 44-61.
In-text example: Garcia et al. (2025) found that quick revision windows improved follow-through.
Why the change makes sense
The shorter rule is not less respectful to coauthors. The full entry still gives readers the information they need to find the source, and databases preserve the complete metadata. The in-text citation has a narrower job: connect the sentence to the source without making the sentence unreadable.
The update also reduces tiny formatting traps. Students used to ask whether the first citation needed all names, whether later citations should shorten, and whether a parenthetical citation followed the same pattern as a narrative one. Now the usual answer is simpler. Three or more authors means first author plus et al. in the places the style calls for it.
The practical rule
If your source has one or two authors, name them according to the style. If it has three or more, expect et al. to appear early. The exact reference list rule still depends on MLA or APA, but the reading experience is the same: shorter citations, less interruption, and fewer old-handout mistakes.
The main trap is mixing eras. Do not use an MLA 7 handout with an MLA 9 works cited page, and do not use APA 6 in-text rules with an APA 7 reference list. Pick the style and edition your class asked for, then let that edition control the whole paper.
