A lecturer (a non-tenured, non-tenure track professor) here at UMBC teaches a few classes covering requirements in a few different departments.  Rather than setting a textbook for the class, this professor requires their students to purchase a $101 access code to an online course site.  This course site has approximately 50 pages of non-peer-reviewed material, and is not published by a major publisher.  Additionally, this lecturer posts the class syllabus, assignment information, and informational links within the same system that houses the previously mentioned "textbook" instead of using the University provided BlackBoard system.  A student only has access to the course site for the duration of the semester.  After the semester, the site is no longer accessible and the End-User License Agreement specifically prohibits copying or printing of the material, so the student cannot sell the "textbook" back to the bookstore, sell or give to another student, or sell using sites like Amazon marketplace or half.com.
