In a recent court case, a copy-shop owner was accused of violating copyright law when, in the preparation of "course packs"—materials photocopied from books and journals and packaged as readings for particular university courses—he copied materials without obtaining permission from or paying sufficient fees to the publishers. As the owner of five small copy shops serving several educational institutions in the area, he argued, as have others in the photocopy business, that the current process for obtaining permissions is time-consuming, cumbersome, and expensive. He also maintained that course packs, which are ubiquitous in higher education, allow professors to assign important readings in books and journals too costly for students to be expected to purchase individually. While the use of copyrighted material for teaching purposes is typically protected by certain provisions of copyright law, this case was unique in that the copying of course packs was done by a copy shop and at a profit.
In the court's view, the business of producing and selling course packs is more properly seen as the exploitation of professional copying technologies and a result of the inability of academic parties to reproduce printed materials efficiently, not the exploitation of these copyrighted materials themselves. The court held that copyright laws do not prohibit professors and students, who may make copies for themselves, from using the photoreproduction services of a third party in order to obtain those same copies at lesser cost.
