Reference Assistance and Circulation at the Map Library

The Map Library staff will gladly assist patrons in identifying and accessing cartographic resources. Only a small percentage of the library's map resources are currently included in the online catalog, I-Share, and patrons may need to use the card catalog in the Map Library to identify map and air photo holdings. Map Library book and journal holdings are included in I-Share. The Map Library staff will also assist with interlibrary loan access to maps and other cartographic resources at other libraries

Most maps circulate for two weeks, with renewals to sixteen weeks. Aerial photographs dated later than 1956 circulate for the same period. Both maps and air photos are checked out at, and returned to, the Help Desk in the Map Library.
