MLA vs. APA: Key Differences & When to Use Each
MLA is the Modern Language Association style, favored in humanities, and APA is the American Psychological Association style, standard in social sciences.
Students mix them up because both require in-text citations and reference lists, yet they look and feel alike at first glance—until a professor marks red ink for “References” instead of “Works Cited.”
Key Differences
MLA uses author-page citations (Smith 23), centers a “Works Cited” page, and capitalizes titles in headline style. APA employs author-date citations (Smith, 2023, p. 23), labels its list “References,” and formats titles in sentence case.
Which One Should You Choose?
Writing about novels, art, or languages? Pick MLA. Reporting psychology, nursing, or business research? Go APA. When in doubt, follow your professor or journal’s submission guidelines.
Examples and Daily Life
Imagine citing Beyoncé’s lyrics in an English paper—MLA italicizes Lemonade and cites the line number. In a marketing study on celebrity influence, APA timestamps the YouTube clip and lists the uploader as author.
Can I switch styles mid-paper?
No. Consistency is required; mixing styles confuses readers and lowers grades.
Do citation generators know the difference?
Good ones prompt you to pick MLA or APA before formatting; always double-check the output.
