I'm happy to consult with instructors on various options for saving students money on course materials. Options for free-to-use course materials include OER, unlimited-user ebooks, and streaming video.
Nationally, I'm a trainer for the Open Education Network (OEN) and one of the instructors for the OEN's Certificate in Open Education Librarianship.
