This depends on whether the Reserve Desk is open or not.
When the desk is OPEN, you must return books directly to the desk. There is a slot on the left-hand side of the desk into which books should be dropped.
DO NOT leave books lying on the desk!
DO NOT return books to the slot at the Butler Circulation Desk on the third floor!
When the desk is CLOSED, you may return books to the outdoor bookbins outside Butler, or to the After Hours Book Drop (accessible only when the library is open 24 hours), located on the wall to the left of the Reserves Office door.
Patrons should be aware that $1/hour reserve fines continue to accrue overnight if reserve items are not returned in the outdoor bookbins or After Hours Book Drop. Do not wait until the Reserves Desk opens to return overdue books!
