Books:
* Italicize the title: This is the most consistent rule across different styles. For example: *To Kill a Mockingbird*, *Pride and Prejudice*, *The Lord of the Rings*.
* Capitalize important words: Capitalize the first and last words, as well as all nouns, pronouns, verbs, adjectives, and adverbs. Articles (a, an, the), prepositions (under, over, to, from, etc.), and conjunctions (and, but, or, etc.) are generally lowercased unless they are the first or last word.
Movies:
* Italicize the title: Similar to books, movie titles are italicized. For example: *Jaws*, *Citizen Kane*, *The Godfather*.
* Capitalize important words: The capitalization rules are generally the same as for books.
Examples:
* Incorrect: To Kill a Mockingbird
* Correct: *To Kill a Mockingbird*
* Incorrect: the lord of the rings
* Correct: *The Lord of the Rings*
* Incorrect: jaws
* Correct: *Jaws*
* Incorrect: the godfather part II
* Correct: *The Godfather Part II*
Exceptions and Considerations:
* Subtitles: Subtitles are treated as part of the title and are italicized along with the main title. For example: *The Lord of the Rings: The Fellowship of the Ring*. Some styles might use a colon, while others might use an em dash. Check the specific style guide for guidance on this.
* Short stories and poems within collections: These are typically placed in quotation marks, while the collection they appear in is italicized. For example: "The Raven" in *Edgar Allan Poe's Complete Works*.
* Style Guides: Always refer to the specific style guide (MLA, APA, Chicago, etc.) required for your assignment or publication. The rules above are general guidelines, but the specifics can vary.
In short, remember to italicize and follow consistent capitalization rules for both book and movie titles. When in doubt, consult a style guide!
