Face, that would be terribly difficult to do, especially for programs like mine (Forensics).
In fields where information changes often, how would you do that in a financially sound way? Plus, there are multiple levels of similar information. The way to do it is make the books REASONABLY PRICED like they are overseas.
There is no reason for every college in the country to not use one textbook for Freshman Biology, for example. Using different texts merely increases the price. It costs far more per book to print 5,000 books than it does to print 50,000 books.
I went to college a long time ago, and don't know if things have changed, but what used to kill my budget was the outside reading. Some courses required as many as 12 or 15 books beyond the basic text. I think one semester I had to buy around 45 books for 5 courses. One question I would have of contemporary students would be are a lot of these books available to read through Kindle or other on-line sources that would reduce your cost? Just wondering as I am not up on the latest technology...
