Q. Is there an elevator in the library?

Yes, there is both a building elevator and an internal library elevator.  Enter Gullixson Hall by the south door off the parking lot.  Go straight until you see the building elevator access on your left.  Take the elevator to floor #2.  The entrance to the library will be down the hall and on your right.

The internal library elevator is located in the bookstack tower.  It reaches all 8 levels of the bookstacks.
