More people write for the Associated Press than for any other news service, and more writers take their style and word-usage cues from this world-famous institution than from any other journalism source. From the when and how of the ampersand to the rules for dashes, slashes, and brackets; from the correct moment for the overused exclamation point to the rules of engagement for the semicolon, The AP Guide to Punctuation is an invaluable and easy-to-use guide to the most important aspect of clear and persuasive writing.
