----------------------------Original message---------------------------- Could you have a lock (s) made for the files so that when Government Documents is not staffed the cases are locked and unavailable at those times? Our collection is in a separate room in the library, and maps are only checked out during the Map Room hours (Mon.-Fri., 8am-4:30pm). In an emergency, a Reference librarian can come down and get a map when the room is closed. I also make arrangements with students to have non-circulating material in the Reference Room in the evenings and weekends. Our pre-1900 maps are in map files with a locking system that I think is "homemade." It predates me. It consists of a rod that slips through the drawer handles and locks at the top with a padlock. People could remove tattle tape and maybe damage the map in the process. Could the maps be encapsulated in plastic with the tattle tape inside the plastic? I don't know if this would defeat the tattle tape. Joyce Ryerson Map Room Baker Library Dartmouth College Hanover, NH [log in to unmask]
