More people write for The Associated Press than for any newspaper in the world, and writers-nearly two million of them-have bought more copies of The AP Stylebook than of any other journalism reference. It provides facts and references for reporters, and defines usage, spelling, and grammar for editors. There are separate sections for journalists specializing in sports and business, and complete guidelines for how to write photo captions, file copy over the wire, proofread text, handle copyrights, and avoid libel. This edition of The AP Stylebook keeps pace with world events, common usage, and AP procedures.
