For those currently attending a university, make sure you take full advantage of the student library. Perhaps I'm preaching to the choir, but I feel like my mind was broadened as much by the books I read as the classes I took, especially the first couple years of undergrad. Also, I'm biased, but if your library doesn't implement
LibX then find out who to bug and do so until they go through the relatively painless process of creating a LibX edition.
I say this because now that I'm dependent on the Wake County Public Library system to fuel my literary appetite, I realize how much I took for granted the awesomeness of the student library at my disposal.
