Textbooks

Trying to find some maxim lighting in the classroom is hard. As my prior post mentions, Amazon is trying to come with a new digital book reader. The one problem I see is the issue of textbooks. One advantage of buying textbooks, for college, is that one can buy a used textbook.

Then I can even sell it back or sell it on Amazon. This way the book does not cost me a lot. Will a used textbook be able to be sold and bought. This is the real question can we get used digital books.
