On the contrary. The text book industry views 2nd hand text books as theft.<p>Currently they do everything in their power to devalue 2nd hand sales, such as pointlessly churning the edition every year or two or even integrating course notes and syllabus for a specific professor. Once they go to e-readers there will be no 2nd hand sales and they can stop wasting resources on pointless editing and profit skyrockets!<p>Until MIT OpenCourseWare puts them all out of business. Good riddance.
