What’s wrong with using course packs?
Course packs for which copyright use permissions have been acquired for all contents are acceptable because paying the fees to obtain those permissions protects the copyright owners’ rights. However, course packs for which permissions have not been obtained for all contents are probably the most common target for copyright violation prosecutions, since such course packs deprive the copyright owners of rightful earnings from their creations. Individual instructors, libraries, copy stores, and even universities have been successfully prosecuted for violations involving course packs. Therefore, written copyright permission must be obtained for all materials in a course pack. Most reputable copy centers and printers will not reproduce course packs without being provided in advance with documentation proving that copyright permission has been obtained because of these cases.
