The history of the AP Stylebook

An ode to my longtime companion, the AP Stylebook... Some of us have had great journalism or English teachers, but none as steadfast as the Stylebook. The first AP Stylebook was produced in 1953 and had 62 pages, according to the Associated Press. The Associated Press Stylebook and Briefing on Media Law, as it is formally know, is edited by longtime AP editor Norm Goldstein and is updated annually. The 2007 edition includes new words like BlackBerry, hip-hop (in 2007?) and Katmandu and in the spirit of new media is available online. I'm a little embarrassed to say I still use mine when referring to state abbreviations. What do you use yours for?
