How to Alphabetize an APA 7 Reference List and MLA Works Cited
Start with complete, checked entries. Identify the word or entry element each style uses for order, apply special cases a plain A–Z sort cannot judge, and finish with a source and formatting review.
Quick answer
APA 7 usually orders a reference list by the first word of each entry, usually the first author’s surname; MLA orders a Works Cited list by the first element of each entry, usually an author surname. Both styles need manual attention for title-first entries, initial articles, group names, numbers, symbols, repeated authors, and coauthors. Sort only after entries are complete and you know which exceptions apply.
APA 7 and MLA alphabetical order at a glance
| Question | APA 7 reference list | MLA Works Cited |
|---|---|---|
| Normal starting point | First word of the entry, usually the first author’s surname. | First element of the entry, usually the author’s surname. |
| No named author | The title is first and supplies the sorting word. | The title is first and supplies the sorting word. |
| Initial A, An, or The | Ignore it in a group-author name and a title-first no-author entry. | For title-first entries, ignore it for order but retain it in the title. |
| Repeated author | Dates and identical author-year titles affect ordering and citation letters. | Solo-author and coauthor entries have additional ordering considerations. |
Source-first worked example: decide the key before sorting
First confirm the responsible author or organization, publication date, title, and other required information from the source record. The examples below are fictional, deliberately abbreviated teaching entries. They are not sources, complete citations, or ready-to-submit references.
Illustrative APA 7 decisions
- A no-author work titled The Atlas of Study Habits is sorted under A because the title is first and “The” is ignored.
- A group author named The North River Institute is sorted under N because initial “The” is ignored in the group name.
- For identical Rivera authors with different years, compare the years: 2021 precedes 2024.
- For two Rivera 2024 works, order the titles first, ignoring initial articles, then assign 2024a and 2024b in that title order and use those letters in the text.
Illustrative MLA decisions
- A title-first entry beginning The Archive is ordered as Archive while retaining The in the title.
- A title-first entry beginning 3 Ways is treated as Three Ways for alphabetization.
- An entry beginning #Bridge is compared from B because the symbol is ignored.
- For a solo/coauthor pair, a Khan solo-author work precedes a Khan-and-Patel work. Consult the required guidance for more complex coauthor sets.
APA 7 reference-list ordering rules
APA Style directs writers to alphabetize references by the first word of the entry, usually the first author surname. A no-author work begins with its title and is alphabetized by that title. See APA Style reference-list setup.
Authors, organization names, and title-first entries
Most entries sort by the first author surname. A group author, such as an organization or committee, also supplies the first word. For a no-author work, the title is first. APA guidance on A, An, and The says to ignore those initial words in a group-author name and in a title-first no-author entry, while retaining the actual name or title in the reference.
Same author, different years and same author-year entries
When identical authors have different years, review the dates as part of the ordering decision. When identical author(s) and year recur, order by title before assigning lowercase year letters. APA says the resulting year-letter combination, such as 2026a and 2026b, must be used in both the reference list and in-text citations. See APA Style on works with the same author and date.
Text and reference correspondence
Alphabetical order is only one final-list check. APA asks writers to compare works cited in the text with the reference list and works in the reference list with citations in the text, subject to stated exceptions. For broad student-paper setup, read the APA 7 format guide.
MLA Works Cited ordering rules
Purdue OWL describes the baseline MLA pattern: alphabetize entries by the first item, usually the author’s last name, and use the title for a work with no known author. See MLA Works Cited Page: Basic Format.
Title-first entries and initial articles
MLA Style Center guidance says title-first entries are alphabetized letter by letter while ignoring initial A, An, or The, yet the article remains at the start of the displayed title. See the title-first guidance.
Numerals, symbols, and coauthors
For a leading numeral, treat the number as though spelled out when alphabetizing; consult MLA Style Center’s numeric-title explanation. Ignore symbols such as hashtags and compare from the first letter in the entry; see its guidance on symbols. The Center also explains that a solo-author work appears before a work by that author and a coauthor; complex coauthor cases need the required MLA guidance.
Edition caution: Some MLA Style Center posts on titles, numerals, and coauthors identify themselves as eighth-edition material and direct readers to the ninth-edition MLA Handbook. Confirm exceptions against the MLA edition and instructor guidance required for the assignment.
How to sort a completed list responsibly
- Confirm the assignment’s style, edition, and any department or instructor rules.
- Complete and verify each entry from the original source. If an entry still needs drafting, use the Citation Generator as a starting point and then check it against the source and required style.
- Mark title-first records, initial articles, group authors, repeated author/date groups, numeral-starting titles, symbols, and coauthor cases.
- Sort My Completed References A–Z only after the lines are complete, then manually review the output.
- Use the Citation Cross-Checker to help compare in-text citations and the list you provide. For RRLs, read the RRL citation-checker guide.
What the local A–Z sorter does—and does not do
The existing local tool orders complete pasted lines A–Z. It does not create citations, reformat an entry, verify a source, interpret all APA or MLA special-case rules, compare in-text citations with the list, or guarantee submission-ready APA/MLA formatting. It is an arrangement aid after entries are complete and manual exceptions have been identified.
Formatting and academic-integrity boundaries
A list can be alphabetized and still be unsuitable for submission. Check the correct heading, spacing, hanging indent, punctuation, capitalization, italics, and required source details against the chosen style and assignment instructions. Cite only sources you actually consulted and can identify. Alphabetical order does not establish that a source is authentic, relevant, correctly interpreted, or evidence for a claim.
Do not treat a generated or copied citation as proof of a source. Open the original publication or reliable record, verify the details, and follow your institution’s academic-integrity and permitted-AI-use policies.
Frequently asked questions
Do I put an APA group author beginning with The under T?
No. APA Style says that initial A, An, and The are ignored for alphabetizing a group-author name, even though the displayed name retains the word.
How do I order two APA works by the same author in the same year?
Alphabetize the titles, ignoring initial A, An, or The, then add lowercase letters in that order and use the same year-letter pair in text citations.
Does MLA alphabetize 10 before 2?
MLA Style Center guidance treats leading numbers in titles as spelled-out words. Confirm final treatment against the edition and instructor guidance required for your work.
Can I submit the sorter output without checking it?
No. Review manual exceptions, formatting, source details, and text/reference correspondence before submitting.
