Comment Professor's Own Books (Score 1) 423
My favorite were the 3-4 classes I took where the professor had written their own text, and obviously choose to use it for the class. They also edited it every year (the worst was one that contained several folklore tales from around the world, and he'd change out 1 or 2 stories every year) so you couldn't sell the $75 thing, and obviously couldn't buy used ones.
