Of course, some professors try to be helpful to students. But of all my professors in 4 years, i probably averaged only one per semester that cared at all. There were actually probably several more that cared, but they were easily swayed by the campus bookstore's pressure to get the newest edition. The managers at the store don't own it, so they just want the easiest path, which is always newest edition. Because they can get them all sent in from one place and then send back any that don't sell. So the managers generally tell professors that they can't get old editions, which is a lie, and the professors just believe them.
