How to write a book name in an essay
Capitalize the first letter of all nouns, verbs, and adjectives in the book name.
Most words in the book name will be capitalized. In addition to the first word, you'll capitalize every significant word.
For example, you would write to kill a mockingbird, the lord of the rings, or wuthering heights. Avoid capitalizing articles, prepositions, or coordinating conjunctions.
