When capitalizing the titles of written works.

When capitalizing the titles of written works, you should generally capitalize the first letter of each word in the title, except for articles (a, an, the), short prepositions (in, at, on, for, of), and conjunctions (and, but, or) unless they are the first word of the title. Additionally, any proper nouns, such as names or places, should also be capitalized. For example, the title "To Kill a Mockingbird" would be capitalized as "To Kill a Mockingbird" rather than "To Kill A Mockingbird".
