What Is The Law Regarding Complimentary Copies?

In 2008, Arizona revised its laws regarding course materials. In particular, a part of Arizona Revised Statatutes § 15–1891 addresses the issues regarding the selling of textbook copies sent for review to instructors. Section E of this statute says

E. A book buyer or vendor of course materials shall not solicit a faculty member or employee of a university under the jurisdiction of the Arizona board of regents or a community college under the jurisdiction of a community college district in this state for the purpose of selling or trading a free sample copy or complimentary teacher editions provided at no charge by a publisher to a faculty member or employee.

In addition to this section of 15-1891, many colleges and universities have adopted policies that restrict the sales of complimentary copies.

So why do the book buyers continue to show up at my door several times a year?
