Antitrust lawyers appear to have picked college textbook publishers as their latest litigation target, as illustrated by a class action filed March 5 in a federal court in Trenton on behalf of students.

The lawsuit targets a distribution model called Inclusive Access, which replaces textbooks with course materials sold by the campus bookstore in electronic format. Critics say the system prevents students from shopping for lower prices at independent bookstores or online. Other suits over the Inclusive Access model are pending in Delaware and South Carolina.
