Title Case Rules

Capitalize all words except short articles, conjunctions, and prepositions (a, an, the, and, but, or, in, on, at, to, for, of, with). Always capitalize the first and last words. Different style guides (AP, APA, Chicago, MLA) have slightly different title case rules for prepositions over 4 letters.
