----------------------------Original message---------------------------- At the University of Arizona we have circulated maps for several years. We barcode maps and have item records for each sheet (actually we're still working on this, but that's where we're headed). Anything that currently isn't in the system when someone wants to check it out, we create what we call an "on the fly" circulation record. When that map (or book etc.) is returned we do the cataloging for it. We do not circulate every map we have in the collection. Any map before 1940 does not go out of the building and any map before 1930 is kept in what we call our "locked case". When we circulate maps, we check them out for 3 weeks in map tubes. If they want to renew them, they have to bring them back in - we do not offer phone renewals for maps. If you have any more questions, please feel free to give me a call.
