General Rules
* Always capitalize the first word of a title. This applies to books, articles, songs, poems, movies, plays, and any other named work.
* Capitalize all major words in a title. These include nouns, pronouns, verbs, adjectives, and adverbs.
* Generally, do not capitalize articles (a, an, the), prepositions (of, in, on, to), conjunctions (and, but, or), or short words like "to" or "as" unless they are the first word of the title.
Specific Examples
* Books: *Pride and Prejudice*, *The Lord of the Rings*
* Articles: "The Future of Artificial Intelligence," "How to Write a Great Essay"
* Songs: "Bohemian Rhapsody," "Imagine"
* Poems: "The Raven," "Ode to a Nightingale"
* Movies: *Star Wars*, *The Shawshank Redemption*
* Plays: *Hamlet*, *Romeo and Juliet*
Exceptions
* Some titles may use all lowercase letters for stylistic reasons. For example, *the sun also rises* by Ernest Hemingway.
* When using a title within a sentence, only capitalize the first word of the title. For example: "I read the book *Pride and Prejudice* last month."
Style Guides
* Specific style guides may have their own rules for capitalizing titles. For example, the Chicago Manual of Style and the MLA Handbook differ slightly in their conventions. Be sure to check the style guide appropriate for your writing.
Remember
Capitalizing titles correctly helps to make your writing clear and professional. When in doubt, consult a style guide or consider the conventions of the specific type of writing you are doing.
