----------------------------Original message---------------------------- Ursula, I understand your problem because as a user of your library I have suffered from it! This suggestion doesn't solve the problem of after-hours access, but helps maybe to track down the missing materials. When I was in grad. school at the Institute of Fine Arts in New York the library was non-circulating, but when we took a book off the shelf we had a sheet that we put in place of the book detailing where it was taken and who took it. If you came upon a sheet instead of the book you were looking for, you knew where it was and could go ask the person if you could borrow the book for a couple of hours if they weren't using it. Faculty were also subject to this system. Of course it wasn't perfect because some people didn't use the sheet, but when we started it was impressed upon us very strictly by the library staff that it was the thing to do. There were about 100-200 students and about 35 faculty. Maybe you could institute this system instead of restricting access, and still keep track of the books. If only a few staff members are causing the problem, it's not fair to restrict access for all. Julia Moore Indianapolis Art Center
