As an out-of-state student, it's hard to see the "budget" approach GT had. However, I will say that many of my professors were well aware of the costs of textbooks, and rarely did it feel like we were required to buy ridiculously expensive books.

It also helps that the library checks out textbooks as well. I think they'll even obtain a copy of a textbook they don't have at the professor's request.

EDIT: Also, the the University System of Georgia has an exchange program that ships unique books between libraries in the state, though this isn't unique to Georgia.
