Titles and Capitalization
Being the geek that I am, it drives me nuts to see improper capitalization in titles. So, I dug out my trusty little (well, not so little) The Chicago Manual of Style and have summarized it for your reading pleasure:
- Always capitalize the first and the last word.
- Capitalize all nouns, pronouns, adjectives, verbs, adverbs, and subordinate conjunctions (e.g. as, because, although).
- Lowercase all articles, coordinate conjunctions (e.g. and, or, nor), and prepositions regardless of length, when they are other than the first or last word.
- Lowercase the to in an infinitive.
I understand some styles allow an exception to rule 3, which is to capitalize all prepositions that are 5 letters or longer in length (e.g. after, among, between).
