What Is MLA Format? A Plain-Language Guide for Humanities Writers

TL;DR — MLA format is a consistent style for humanities papers that governs three things: how your pages look, how you cite sources in the text, and how you list those sources on a "Works Cited" page. Master those three and you have MLA.

If you are writing in English literature, languages, philosophy, or the arts, your instructor will most likely ask for MLA style. The letters stand for the Modern Language Association, the group that publishes the guidelines. MLA is now in its ninth edition, and while details shift between editions, the core ideas stay the same. This guide walks through what actually matters so you can format a paper without second-guessing every line.

What MLA Format Is For

Citation styles exist to solve a simple problem: readers need to know where your ideas came from. When everyone in a field uses the same system, a reader can glance at a citation and immediately understand it. MLA also helps you give honest credit, which protects you from accidental plagiarism.

Think of MLA as three connected layers:

Page setup — the look of the document itself.
In-text citations — short pointers placed where you use a source.
Works Cited — the full list of sources at the end.

Each layer points to the next. An in-text citation is meant to send the reader to the matching entry on your Works Cited page. Keeping that link intact is the single most important habit in MLA.

The first-page setup is covered line by line in MLA heading and header. Entry-by-entry examples for the last page are in the MLA Works Cited guide.

Setting Up the Page

MLA pages follow a predictable, clean layout. Set these once and you rarely touch them again:

Use a readable font such as Times New Roman, size 12.
Double-space the entire paper, including quotations and the Works Cited list.
Set one-inch margins on all sides.
Indent the first line of every paragraph half an inch.
In the top right corner of every page, place your last name and the page number, like Okonkwo 4.

MLA does not use a separate title page by default. Instead, you place a four-line heading in the top left of the first page, then center your title below it.

Notice the date is written day-month-year, and the title is in regular text, not bold or underlined.

Citing Sources in the Text

When you quote, paraphrase, or summarize a source, you add a short citation right where the borrowed material appears. The standard MLA citation gives the author’s last name and the page number, with no comma between them.

Worked example. Suppose you are using page 12 of a book by Daniel Reyes:

Reyes argues that stage lighting “does more emotional work than any line of dialogue” (12).

Because the author’s name already appears in the sentence, you only need the page number in parentheses. If you had not named the author, you would write it this way:

If this is useful, Writing an APA Research Paper: A Clear, Step-by-Step Guide is a natural next step.

One critic claims that lighting “does more emotional work than any line of dialogue” (Reyes 12).

A few practical rules:

The period goes after the closing parenthesis, not before.
If a source has no page numbers (a web article, for example), simply give the author’s name: (Reyes).
For two authors, name both: (Reyes and Cho 88).

Building the Works Cited Page

The Works Cited page is a complete, alphabetical list of every source you cited. Start it on a new page, center the words Works Cited at the top, and list entries alphabetically by the author’s last name. Each entry uses a hanging indent: the first line sits at the margin, and following lines are indented half an inch.

MLA 9 uses a flexible template of “core elements.” You assemble each entry in this order, including only the parts that apply:

Author.
Title of source.
Title of container (the larger work, such as a journal or website).
Other contributors.
Version.
Number.
Publisher.
Publication date.
Location (page range, URL, or DOI).

Worked example — a book:

Reyes, Daniel. Light and Shadow on the Modern Stage. Harbor Press, 2019.

Worked example — an article on a website:

Cho, Aiko. “Reading Silence in Theatre.” Stage Notes, 4 Mar. 2021, stagenotes.example/silence.

Italicize titles of long works (books, journals, websites) and put titles of shorter pieces (articles, poems, chapters) in quotation marks.

Common Mistakes to Avoid

A handful of slips show up again and again. Watch for these:

Mismatched citations. Every in-text citation needs a matching Works Cited entry, and every entry must be cited somewhere in the paper. Check both directions.
Putting a comma before the page number. It is (Reyes 12), not (Reyes, 12).
Forgetting the hanging indent. A flush-left Works Cited list is the most common formatting error.
Listing sources in the order you used them. They must be alphabetical, not chronological.
Adding a “p.” before page numbers in MLA. That belongs to other styles; MLA uses the number alone.
Treating the heading as a title page. The four-line heading goes on the first page of your essay, not on a page by itself.

A Quick Workflow

To keep MLA from feeling overwhelming, build it as you go rather than at the end:

Set up the page layout before you write a word.
Each time you borrow material, add the in-text citation immediately.
The moment you cite a source, create its full Works Cited entry.
Before submitting, read your Works Cited list against your in-text citations to confirm every pair matches.

Handled this way, formatting becomes a steady background task instead of a last-minute scramble. MLA rewards consistency more than memorization: once your page setup, in-text citations, and Works Cited entries all speak the same quiet, orderly language, your reader can focus on what you actually have to say.

Frequently asked questions

How do you cite a source in text in MLA format?

Put the author’s last name and the page number in parentheses with no comma between them, and place the period after the closing parenthesis: (Reyes 12). If the author is already named in the sentence, give only the page number. For a web source without pages, use the name alone, and for two authors write (Reyes and Cho 88).

Does MLA format require a title page?

No. Instead, put a four-line heading in the top left of the first page with your name, your instructor’s name, the course, and the date written day-month-year, then centre the title below it in plain text. Your last name and the page number go in the top right corner of every page.

How do I format a Works Cited page in MLA?

Start a new page, centre the words Works Cited at the top, and list every cited source alphabetically by author’s last name with a hanging indent. Build each entry from the core elements in order: author, title of source, container, contributors, version, number, publisher, date, location. Italicise long works such as books and put shorter pieces such as articles in quotation marks.
