How to Use MLA Referencing

MLA replaced source-type templates with one flexible system, which is easier once you stop looking for a template.

MLA is the standard in literature, languages and much of the humanities. Its ninth edition works differently from styles built around fixed templates: instead of a separate pattern for each source type, it uses a single set of elements assembled in a consistent order. Once that logic clicks, unusual sources stop being a problem.

In-text citations are author and page

Unlike author-date systems, MLA cites location rather than year. The basic parenthetical form gives the author’s surname and the page number with no comma: (Okafor 14). Where the author is named in your sentence, only the page appears: Okafor argues that attendance declined (14).

For sources without pages — web pages, films — omit the number rather than inventing one. Where a work has numbered sections, paragraphs or timecodes, cite those with the appropriate label.

The containers system

MLA 9 treats every source as a work that may sit inside one or more containers. An article sits in a journal; the journal may sit in a database. A song sits in an album; the album may sit in a streaming service. You describe the work, then each container in turn.

• Author. Surname, First name.
• Title of source. In quotation marks for parts, italics for whole works.
• Title of container, italicised.
• Other contributors, editors, translators.
• Version, Number, Publisher, Publication date, Location.

Each element is followed by the punctuation shown, and elements that do not apply are simply omitted. This is why MLA handles unusual sources gracefully — you are describing what exists rather than hunting for a matching template.

Works Cited, not Bibliography

The list is headed Works Cited and contains only sources actually cited. It is alphabetical by the first element of each entry, usually the author’s surname, with a hanging indent. Where a source has no author, the title takes that position and is alphabetised accordingly, ignoring initial articles.

Multiple authors and repeated authors

Two authors are both named, joined by “and”. Three or more use the first author followed by “et al.” Where you cite several works by the same author, the in-text citation includes a shortened title to distinguish them: (Okafor, “Attendance” 14).

In the Works Cited list, repeated authors are replaced by three hyphens and a full stop in some conventions, though MLA 9 permits repeating the name, which is clearer.

Quoting in the humanities

MLA disciplines quote more than most, so the mechanics matter. Short quotations run within your sentence in double quotation marks with the citation after the closing mark and before the full stop. Quotations of more than four lines are indented as a block without quotation marks, with the citation after the final punctuation.

Poetry quoted inline marks line breaks with a forward slash, and verse citations give line numbers rather than pages.

Formatting the paper

MLA specifies the document as well as the citations: double spacing throughout, a legible font, one-inch margins, and a header with your surname and page number. There is no title page in standard MLA — your name, instructor, course and date appear at the top of the first page, followed by a centred title.

Where marks are commonly lost

The errors are consistent and mechanical, which makes them easy to check for.

• A comma between author and page in the parenthetical citation.
• Italicising an article title rather than the journal.
• Missing hanging indents in the Works Cited list.
• Citations placed after the full stop rather than before.
• Entries in the list that are never cited, or citations with no entry.

Use a manager, then verify

Reference software supports MLA but frequently mishandles containers, particularly for database-hosted articles and web sources. Treat generated entries as drafts, and check a sample against the element order before trusting the rest.

When in doubt, describe the source

The containers system means there is almost always a defensible way to cite an unusual item — a podcast episode, a museum object, a social media post, an AI tool. Work through the elements in order, include what applies, omit what does not, and be consistent across similar sources. Consistency is what markers assess when a source type has no obvious precedent.

Notes and bibliography, and when to use them

MLA is primarily a parenthetical system, but it permits endnotes for material that would interrupt the argument — a substantive aside, a note on a textual variant, a comment on a source’s reliability. These are content notes rather than citation notes, and they should be genuinely necessary; a paper carrying twenty endnotes has usually put the argument in the wrong place.

Where a course asks for a bibliography of works consulted in addition to the Works Cited list, the two are formatted identically and differ only in what they contain.

Build the list as you write

Add each entry when you first cite the source, with the page numbers you drew on. Reconstructing a Works Cited list at the end from a folder of PDFs is slow and error-prone, and it is where most missing entries originate. Before submitting, check in both directions — every citation has an entry, every entry is cited.
