Mla Purdue Style Guide: Formatting And Citations

Mastering MLA style doesn't require guessing margins or memorizing punctuation rules for every source type. The Modern Language Association guidelines focus on a simple core structure: present your paper consistently and credit your sources clearly so readers can locate them without friction.

Whether you're writing a short literary analysis or a senior thesis, this guide walks through document setup, in-text parenthetical references, and Works Cited page creation based on the Modern Language Association standards and the Purdue Online Writing Lab.

Setting Up Your Document Layout

Before writing a single sentence, configure your word processor to meet standard MLA layout requirements. Clean, uniform presentation keeps the focus on your arguments rather than your styling.

• Paper and Margins: Use standard 8.5 x 11-inch white paper. Set one-inch margins on the top, bottom, left, and right sides.
• Font and Size: Choose a readable, standard font like 12-point Times New Roman, Arial, or Calibri. Avoid stylized scripts or decorative fonts.
• Line Spacing: Double-space the entire document, including block quotes, endnotes, and the Works Cited page. Don't add extra blank lines between paragraphs or headings.
• Paragraph Indents: Indent the first line of every paragraph one-half inch using the tab key, not the spacebar.
• Page Numbers: Number all pages consecutively in the upper right-hand corner, exactly one-half inch from the top edge and flush with the right margin. Type your last name immediately before the page number (for example, Smith 4).

The First Page Header

MLA style doesn't require a separate title page unless your instructor explicitly requests one. Instead, include a four-line block in the upper left-hand corner of your first page, double-spaced:

1. Your full name
2. Your instructor's name
3. The course name or number
4. The date (written in day-month-year order, such as 14 November 2026)

Drop down another double space and center your paper's title using standard title capitalization. Don't underline, italicize, or place your title in quotation marks. Drop down one more double space and begin your opening paragraph.

Writing In-Text Citations

When you quote, paraphrase, or summarize another writer's ideas, you must acknowledge the source right inside your text. MLA uses parenthetical citations placed at the end of the sentence, usually right before the terminal punctuation.

The basic rule is simple: provide the author's last name and the specific page number where the information appears.

• Direct Quote: When you use exact words, enclose them in quotation marks and place the citation immediately after: As Morrison notes, memory is "strange and powerful" (42).
• Paraphrase: Even when you put an author's concept into your own words, you must cite the source: Memory shapes our perception of historical trauma (Morrison 42).
• Author Named in Text: If you mention the author's name in your sentence, don't repeat it in the parentheses: According to Morrison, memory is "strange and powerful" (42).

Handling Multiple Authors and Missing Data

Real-world research sources don't always feature a single author with clear page numbers. Adjust your parenthetical citations based on these common variations:

• Two Authors: Include both last names connected by and: (Smith and Jones 78).
• Three or More Authors: List the first author's full name followed by et al.: (Brown et al. 112).
• Corporate or Government Author: Use the organization name as the author: (World Health Organization 15).
• No Author: Use a shortened version of the source title in quotation marks: ("Global Economic Trends" 4).
• Digital Sources Without Pages: If a website or video lacks page numbers, omit the number entirely and rely on the author's name: (Garcia).

Building the Works Cited Page

Every source you cite in your text must appear on your Works Cited page at the end of your paper. Start this page on a new sheet of paper, maintaining your running header with your last name and page number. Center the title Works Cited one inch from the top.

Entries are arranged in alphabetical order by the author's last name. If a source has no author, alphabetize it by its title, ignoring initial articles like A, An, or The.

Every entry uses a hanging indent: the first line of each citation sits flush with the left margin, while any subsequent lines in that citation indent one-half inch.

Core Elements of a Citation

The 9th edition of the MLA Handbook relies on a universal template built around nine core elements. You find these pieces on the source and string them together using standard punctuation:

1. Author.
2. Title of source.
3. Title of container,
4. Other contributors,
5. Version,
6. Number,
7. Publisher,
8. Publication date,
9. Location.

Common Source Citation Examples

Applying the core element template yields clean, consistent citations for the formats you use most often.

• Print Book: Didion, Joan. The Year of Magical Thinking. Alfred A. Knopf, 2005.
• Journal Article from a Database: Greenblatt, Stephen. "Cultural Mobility." The Norton Anthology of Theory and Criticism, edited by Leitch et al., W. W. Norton & Company, 2018, pp. 1540-45.
• Web Page: Lowe, Sarah. "Understanding Modern Architecture." Art History Online, 12 Mar. 2024, www.arthistoryonline.org/modern-architecture. Accessed 22 Oct. 2026.

Notice that URLs are included for web sources, but you should omit the https:// prefix for cleaner presentation. Always include an access date if the online source lacks a stable permanent publication date or if it changes frequently.

Common Mistakes to Avoid

Even experienced writers trip up on specific stylistic nuances. Watch out for these frequent errors:

• Using Footnotes for Citations: Unlike Chicago style, MLA relies strictly on parenthetical in-text citations. Save footnotes or endnotes for brief explanatory content or acknowledgments.
• Altering Quotations Carelessly: If you change a word inside a quote to fit your sentence grammar, enclose your alteration in square brackets. If you omit words, use an ellipsis with a space on either side.
• Alphabetizing by First Name: Always alphabetize Works Cited entries by the author's last name, never the first.
• Forgetting Double Spacing: Students often single-space block quotes or reference lists. Every line of an MLA paper must be double-spaced.

Frequently Asked Questions

Do I include a title page for a standard MLA research paper?

No. Unless your instructor specifically requests a separate title page, start your paper directly on the first page with the four-line header block in the upper left corner, followed by your centered title.

How do I cite a source with no publication date?

When a credible web page or digital document lacks a publication date, simply omit the date from your citation. Include an access date at the very end of the entry so readers know when you viewed the material.

Should I include URLs in my Works Cited page?

Yes, for online sources without a physical print counterpart, include the URL at the end of the citation. Drop the https:// or http:// prefix to keep the citation visually clean unless your instructor requires the full address.

How do I format long quotes in MLA style?

If a prose quotation runs longer than four lines, set it off as a block quote. Indent the entire block one-half inch from the left margin. Drop the quotation marks, and place your parenthetical citation after the final punctuation mark of the quoted sentence.
