The Modern Language Association (9th edition) establishes a unified documentation framework based on nine core container elements for humanities research. Mastering MLA 9th edition requires configuring four-line first-page headings, running headers, author-page parenthetical attributions, and hanging-indented Works Cited pages without manual formatting errors.

The Modern Language Association (MLA) updates its guidelines periodically to reflect how we research and write today. If you’re used to older versions, transitioning to the MLA 9th Edition can be confusing. What changed? What stayed the same? And how do you ensure your paper meets the current standards?

This comprehensive guide covers everything you need to know about the MLA 9th Edition, giving you the confidence to write and cite correctly.

The Core Philosophy: Containers

The biggest shift in recent MLA editions, which continues strongly in the 9th Edition, is the concept of “containers.” Instead of trying to memorize a specific citation format for a book, a journal, a website, and a YouTube video separately, MLA uses a universal set of core elements.

When you cite a source, you look for these core elements in a specific order: Author, Title of source, Title of container, Other contributors, Version, Number, Publisher, Publication date, Location.

A “container” is the larger whole that holds the source. For example, if you cite an article (the source) in an academic journal (the container), you follow this pattern. This flexible system makes it easier to cite emerging media types.

Key Updates in the 9th Edition

While the 9th Edition builds upon the 8th, it offers clearer guidelines and more examples for complex scenarios.

More Guidance on Inclusive Language: The 9th Edition places a stronger emphasis on using inclusive and respectful language, providing detailed advice on avoiding bias regarding race, ethnicity, religion, gender, and sexual orientation.

Expanded Rules for Online Sources: With digital media evolving rapidly, the new edition offers more robust examples for citing things like social media posts, streaming video, and online forums.

Clarification on URLs and DOIs: The guidelines for including URLs and Digital Object Identifiers (DOIs) have been refined to ensure links are as helpful and stable as possible.

Formatting Your Document

The physical layout of your paper remains consistent with previous editions. You must maintain 1-inch margins, a legible 12 pt font (like Times New Roman), and double spacing throughout.

Remember the first-page heading: Name, Instructor, Course, Date. And don’t forget the running header in the top right corner with your last name and page number.
