KestrelSWard , Listening to a webinar about how course material costs affect students other than simply financially, and one thing they touched on is the temporary nature of a lot of course materials these days. They're e-books that you rent and then get returned, or physical book rentals, or they're so expensive you have to sell them back to the bookstore to recoup the loss of money. And I hadn't really grokked how much mroe true this was now?
