Huzzah for libraries!
I'm actually a college student in pursuit of a job as a librarian and a college that offers a library sciences program. The libraries in my area are pretty nifty, and I think they really helped to shape who I am. My college library, however, is the worst library I've ever come across and their system of arranging books infuriates me (seriously, why can't they use the Dewey Decimal system like most places?).
Also, Mar0, as a book lover I must say that sometimes libraries just don't do it for me. There are some books that I just have to own. Similarly, there are just some books that I feel I must buy brand new. Plus, I tend to read very obscure titles that none of the libraries have a copy of.
