For those under deadlines or of a more nocturnal disposition, there is quite a supply of academic literature at the Night Library. Wait until the sun has gone down and the keeper wakes, or suffer his sharp glares.
Students can’t go in, of course, it’s much too narrow, but if you know the books you need the librarian can fetch them for you. The service is free, but a few offerings of snacks or drinks will please the old owl immensely. Books may also be donated here, though duplicates will be stored in one of the other trees.
Make sure to return your book on time! The librarian may well fly into your dorm and whisk it clean off your desk, even if you’re using it.
