The Associated Press is giving away a limited number of its 2015 AP Stylebooks to schools or journalism groups that can’t afford them. However, you do have to pay for postage but that should be minimal when compared to the cost of one of these books.
The application is short and should take you only a few minutes. I received five Stylebooks from them a couple of years ago and that greatly updated the library of 2009 AP Stylebooks that I’ve used in my journalism courses.
Here is the link for the books. http://www.apstylebook.com/?do=donations
