What about used books sold between students?

Also, what's with making a different edition every 1-2 years so you can make sure to soak up more money out of poor college students?!

Well with computer science textbooks (dealing with the Web, and Microsoft Office apps) you have to update the books to keep up with the changes in the software. It keeps me busy and employed.

Oh, I should also add regarding the used textbook market that professors want new editions every couple of years in order to keep students from sharing answers from one year to another. So there's a desire to kill the used textbook market from both the professors and publishers.
