This is the title of my paper, and I want to make sure the capitalization is correct.

Small Town vs. Big City: Which is better?

To ensure correct capitalization in your paper title, you can follow the standard rules of title case. In title case, the first and last words of the title should always be capitalized, regardless of their length or part of speech. Additionally, all major words in the title, such as nouns, verbs, adjectives, and adverbs, should also be capitalized. Minor words, such as articles (a, an, the), conjunctions (and, but, or), and prepositions (in, on, at) are typically not capitalized unless they are the first or last word of the title.

Applying these rules to your paper title, "Small Town vs. Big City: Which is Better?", the correct capitalization is as follows:

- Small (adjective)
- Town (noun)
- vs. (preposition)
- Big (adjective)
- City (noun)
- Which (pronoun)
- Is (verb)
- Better (adjective)

Therefore, the capitalization in your title is correct.
