MLA in-text citation, as detailed by Purdue OWL, is a system for briefly crediting sources within your paper using the author-page method. This guide explains how to format parenthetical citations, handle quotations and paraphrases, manage multiple authors and sources with the same author, cite indirect sources and online materials, and avoid common mistakes. Designed for students and researchers in the humanities, it provides a consistent, verifiable way to point readers to your Works Cited list.
Core Principles of MLA In-Text Citation
The central purpose of MLA in-text citation is to point readers to the full source in your Works Cited without interrupting your prose. It relies on two linked elements: a brief citation in the text and a complete entry on the Works Cited page. The key components include the author’s last name and the page number, placed at the end of the sentence or clause being cited. When quoting, paraphrasing, or summarizing, these elements signal exactly where the idea or wording originates. Built for clarity and flexibility, this style adapts to print sources, web sources, and media, all while keeping the reader’s experience smooth.
Standard Author-Page Format
For most sources with an identifiable author, MLA in-text citation requires the author’s last name and the page number in parentheses. No punctuation is needed between the two elements, and the period follows the closing parenthesis. If the author is mentioned in the sentence, include only the page number in parentheses. This approach keeps attribution visible but unobtrusive, making it easy for readers to trace ideas back to the Works Cited.
Basic Examples
- Parenthetical: Modernism emphasizes fragmentation (Smith 23).
- Narrative: Smith argues that modernism emphasizes fragmentation (23).
Quoting and Block Quotations
When quoting directly, integrate short quotes (fewer than four lines of prose or three lines of verse) using quotation marks and an in-text citation. Long quotations (four or more lines of prose or three or more lines of verse) are set off as block quotes without quotation marks, indented one inch from the left margin. The parenthetical citation appears after the final punctuation of the block quote. Maintain original line breaks for poetry and ensure the quote supports your analysis rather than displacing your voice.
Short and Long Quote Format
- Short quote: Morrison describes memory as “a way of holding onto what you thought you had…lost” (12).
- Block quote: Morrison reflects:
"Memory is a way of holding onto what you thought you had…lost… It may weaken, but it does not fade, not truly, and the marks it leaves attest to its power.
" (12)
Paraphrasing and Summarizing
Paraphrasing requires an in-text citation even though the words are your own, because the idea remains borrowed. Place the author-page citation where it naturally fits, typically at the end of the paraphrased sentence. Avoid patchwriting by genuinely restating the idea in your own syntax and vocabulary, then cite the page when relevant. Accurate paraphrasing shows you understand the material and gives proper credit without unnecessary quotation marks.
Paraphrase Checklist
- Use your own structure and vocabulary.
- Retain the original meaning precisely.
- Include an author-page citation at the appropriate point.
Multiple Authors and Same Author Sources
For sources with two authors, include both last names joined by "and" in narrative or "&" in parentheses. For three or more authors, use the first author’s last name followed by "et al." When multiple works by the same author appear in the same sentence, include the title (or a shortened form) in the parenthetical citation to avoid confusion. This clarity prevents misinterpretation and ensures each source is distinctly traceable.
Multiple-Source Examples
| Scenario | In-Text Citation | Notes |
|---|---|---|
| Two authors | (Raymond and Singh 45) | Or Raymond and Singh argued… (45) |
| Three or more authors | (Chen et al. 78) | Use et al. in both forms |
| Same author, different works | (Ellison 12) and (Ellison, Invisible Man 45) | Add a shortened title when needed |
Indirect Sources, Online Materials, and Common Knowledge
When the original source is unavailable, cite the source you consulted, noting the original work indirectly. For web sources without page numbers, use section headings, paragraph numbers, or other stable markers, or simply omit the number. Generally, omit the date in web citations unless the site uses numbered paragraphs or dates in headings. Well-established facts and common knowledge do not require in-text citation, but when in doubt, cite to maintain academic integrity and allow readers to verify your claims.
Nonprint and Indirect Source Guidance
- Online article without page numbers: (Smith par. 5) or (Smith).
- Two or more works in one parenthesis: (Smith 23; Kumar 112).
- Indirect source: (qtd. in Ramos 33) to show you saw the idea in another’s work.
Avoiding Common Pitfalls
Common errors include omitting page numbers when available, misplacing periods inside citations, and using generic citations without author or page. Always match in-text citations to the Works Cited exactly, preserve quotation marks around exact wording, and ensure paraphrases are truly original in structure. Consistent punctuation, accurate page references, and clear integration of sources protect your credibility and reader trust.
Quick Reference: Do and Don’t
| Do | Don’t |
|---|---|
| Match Works Cited entries exactly | Use a Works Cited entry without an in-text citation |
| Use author-page for standard citations | Place the period inside the parenthesis |
| Cite indirect sources with "qtd. in" | Rely on URLs without stable locators |
| Paraphrase with your own structure | Patchwrite or change only a few words |
