TITLES OF ARTICLES

For print titles, generally capitalize all words (nouns, pronouns, verbs, adverbs, and adjectives) except conjunctions and prepositions of three letters or fewer, articles, and the to of infinitives unless aesthetically displeasing. Don't capitalize a, an, and, at, but, by, for, in, of, on, or, so, the, to, and up. Capitalize Too and Yet. Prepositions are capitalized when they are part of a verb, such as "believe in," "brought up," or "take off." 

Capitalize the first and last words of a title, even if they would not normally be capped. Words paralleling others that are capped should themselves be capped.

Use a colon or dash when one element amplifies another and a comma when one element is in apposition to another.

In hyphenated compounds, each word may be capped, depending on appearance.
