The AP Stylebook, formally known as The Associated Press Stylebook and Briefing on Media Law, is a style guide published by the Associated Press (AP). It provides standardized guidelines for grammar, punctuation, capitalization, and usage in news writing. First published in 1953, the AP Stylebook is widely used by journalists, editors, public relations professionals, and news organizations in the United States and internationally.
The guide is updated annually to reflect changes in language, emerging technologies, societal developments, and journalistic practices. Topics covered include word usage, inclusive language, titles, numerals, abbreviations, and ethical considerations in reporting. The AP Stylebook also includes a section on media law, offering guidance on libel, privacy, and copyright issues relevant to journalists.
The publication is available in print, online, and through a mobile app, with the online version offering additional resources such as a searchable database and updates between editions. The AP Stylebook is considered a primary reference in American journalism and is often used in journalism education.
The Associated Press, founded in 1846, developed the stylebook to ensure consistency and clarity in news reporting across its vast network of member newspapers and media outlets. While not the only style guide in journalism (others include the Chicago Manual of Style and The New York Times Manual of Style and Usage), the AP Stylebook is among the most influential in daily news publishing.
