Many publishers produce "content cartridges" for Learning Management Systems, (LMS) to accompany their textbooks. The cartridges are generally made available by the publisher in a downloadable zip file format which can be uploaded into an LMS. To find out if your textbook publisher provides cartridges which are compatible, contact your local publisher's representative.

Courses that use an e-pack or course cartridge may provide a blanket statement acknowledging that a significant portion of the course materials came from the publisher rather than include individual citations for each instance of publisher materials.
