The Arizona State Senate has passed a bill requiring that textbook publishers inform professors about the cost and contents of new textbooks, so that profs can make informed choices when assigning books for classes. 

The passage of the bill was the result of intensive lobbying by the Arizona Student Association, and its passage was hailed by student activists.

Ten states currently have similar legislation in effect. The Arizona bill was passed by large bipartisan majorities in both houses of the state legislature, and student leaders expect governor Janet Napolitano to sign it.
