AP Style Guide: Purdue Online Writing Lab
- Names: Full name on first reference. Only last name with no titles after that.
Example: Adam Chiara, a professor at UHart, taught a class on AP style. Chiara knew his students would dislike him for it.
- Titles: Capitalize a title if it’s before the name. If used after, it’s lowercase.
Example: Professor Adam Chiara is considering running for president. Chiara has only been a professor; he has never been a governor or the president.
- Quotes: Commas and periods inside the quotation mark. If the quote is the beginning of the sentence, the first letter is capital. If the quote is a continuation, the first letter is lowercase. More details on quotes.
Example: “This challenge is the real deal,” Chiara said. He said it’s not the time that’s the problem. “It’s hard for me to get up early in the morning.”
- Location: Town, Conn.
Example: He was born in Hartford, Conn., where he still lives today. He wants to move to Danbury, Conn.
However, if you just mention the state, it is written out.
Example: He lives in Connecticut.
- Dates: Oct. 21
The event is on Oct. 21, at the XL Center.
However, if there is not date, the month is written out.
Example: He was born in October.

- Time: 5 a.m. 3:15 p.m.
