If you don't mind allegorical deconstructions of academia, and none of them light reading, there are:
- Magister Ludi/The Glass Bead Game by Hermann Hesse
- Giles Goat-Boy by John Barth
- Anathem by Neal Stephenson
Like Vonnegut, Barth was first recommended to me by someone who could easily have been a character from one of his books.
