Schools and classes change over years. Textbooks get replaced with newer ones, different structures ones, etc.....
What happens to old high school textbooks? Info is still good stuff. Where are the old history and geometry books from 20 years ago when I was in high school?
Are they used somewhere, able to be picked up dirt cheap? Many would be great books to have on the shelf to reference from time to time.
Anybody have a clue where they go? I googled, but its hard to track down "old" ones versus current ones being sold used.
