AP Citation Style

The Associated Press Stylebook and Libel Manual is not specifically a citation style manual, but more a usage guide for the print communications industry. It was first published in 1977 to provide a consistent standard of grammar, spelling, and usage rules for newspapers. Having such a standard reduces bias and enhances product quality. Today, nearly all U.S. newspapers, magazines, and most public relations firms use the style guide to maintain concise readability.
