----------------------------Original message---------------------------- We recently conducted an inventory of the USGS topo collection for our state (Alaska) for the first time in about a decade. We were frustrated to find 25% of these maps are missing. Our maps are available to the public in flat files located next to the Government Documents reference area. The nearby Documents office is staffed 8-5 M-F. We have considered putting tattle tape strips on the maps, but they can be easily removed. We do not want to make the maps a closed collection. I would appreciate any suggestions or ideas on how other libraries have handled the security problem for the map collection.
