Textbook publishers screw the last fifty bucks out of every book they sell to a captive audience. It's an outrage, really. And then they put out a "new" edition every other year so you have to buy new stuff all the time. Usually the only thing that's different between editions is pagination. Sometimes not even that. This past semester a publisher sent me a 2nd edition of a text of Shakespeare that was identical, even down to the pagination, with the 1st edition. Oh--sorry, there was one difference: the price was 20 bucks more. I hate textbook publishers.
