NOTE: All books are in the stacks area in the back half of the library unless otherwise indicated. Any book with a "REF" prefix in its call number is in the reference room (the room to your left as you enter the library) and must stay in the library at all times, although you are welcome to photocopy out of it. Any book with the "OVERSIZE" prefix in its call number is in the oversized section along the very back wall of the library next to the vertical file drawers. When finished using books that you have not checked out, please return them to the circulation desk so that we can count them for the purpose of compiling usage statistics. :-) Thanks!
