In both titles and subtitles of works mentioned in the text of a paper, major words such as nouns, pronouns, verbs, adjectives, and adverbs should be capitalized. Minor words such as articles, prepositions, and coordinating conjunctions are not capitalized unless they are the first or last word of a title or subtitle. (In APA style, also capitalize all words of four or more letters.)

Capitalize the second part of a hyphenated term in a title if it is a major word but not if it is a minor word. Capitalize chapter titles and the titles of other major divisions of a work following the same guidelines used for titles of complete works.
