You _can_ just walk into the library at the University of Wisconsin. There is only one library on the Madison campus (Memorial Library) that requires an ID to enter. That leaves 49 other libraries on campus open to anyone.
Fair enough, I was thinking of Memorial. And, for that matter, I was thinking of one particular library at NC State which may have been for math and science only.
Nah, at NC State, D. H. Hill (the main library) is open to the public during normal hours. The "satellite libraries" are Design, Textiles, Natural Resources, and Veterinary Medicine, and I'm not sure whether those are open access or not.
I also don't know whether the new Hunt Engineering Library is going to be public access or not, but I hope it will be because it's going to be awesome.
