About APA Title Case
APA title case is defined by the American Psychological Association's Publication Manual, 7th edition (2020). It is the dominant style in psychology, education, social sciences, nursing, and business research journals. APA's most distinctive rule is that all prepositions — regardless of length — stay lowercase. Words like "about," "between," "through," and "without" that Chicago would capitalize remain lowercase in APA. This makes APA one of the most conservative title case styles. The style is designed for consistency and clarity in academic publishing, where authors regularly write long, complex titles with many prepositions and conjunctions.

Common APA Edge Cases
- "to" in infinitives is treated as a preposition and stays lowercase: "How to Write a Paper," not "How To Write a Paper."
- "Is," "are," "be," and other short verbs are always capitalized — they are verbs, not prepositions.
- The first word after a colon or em dash is always capitalized, even if it is an article or preposition.
- Hyphenated compounds: capitalize both parts if both are major words (e.g., "Self-Report," not "Self-report").
- Proper nouns within a title retain their original capitalization regardless of position.
APA vs MLA
APA and MLA are the two most similar title case styles — both lowercase all prepositions regardless of length, and both capitalize the same categories of major words. The practical difference appears mainly in reference lists: APA uses sentence case for article and book titles in the References section, while MLA uses title case throughout the Works Cited list. For title case applied to headings and paper titles, the two styles produce nearly identical results.
