Background: Affiliated Bookstores.
Bookstores affiliated with public higher education institutes have certain requirements relating to the sale of course materials, such as textbooks and access codes to homework websites. Affiliated bookstores must sell unbundled books, disclose the cost of materials to faculty and staff, disclose how new editions vary from previous editions, and promote book buy-back programs. Finally, with some exceptions, students must be provided with information on required course materials including title, authors, edition, price, and the International Standard Book Number (ISBN) four weeks before the start of the class. Faculty and staff take into account cost when assigning course materials such as adopting the least expensive edition, free or open textbooks when available, or working with librarians to use free online and library resources.
