The Associated Press guide to punctuation

the long version

"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. In the no-nonsense, authoritative tradition of the best-selling AP Stylebook, the top editors at the AP have now written the definitive guide to punctuation. 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"--Publisher description.
