The print AP Stylebook is published every other year. The current version is the AP Stylebook, 55th Edition, which went on sale in May 2020. The next edition is scheduled to publish in May 2022.
We used to release a new spiral-bound book every spring. We changed to publishing every other year in 2020.
AP StyleGuard for Word, AP StyleGuard for Outlook and AP Lingofy are updated throughout the year.
