Not sure how this is now, but Germany 10 years ago my professors would either give out lecture notes (reproduced at printing cost locally and/or as pdf) or choose books that the library had. In one case, a professor used a book he had written for a programming/algorithms course. "I'll make sure the library gets a bunch of those before the first homeworks are due." And sure enough, they had enough for everyone in class. Fix your education system. Seriously, it's embarassing.
