A Regional Map Collection (1860-1972) is housed in Special Collections & University Archives (SCUA) on the third floor of Vasche Library. This collection includes historical maps of regional cities, such as Turlock, Modesto, Riverbank, etc., and the counties of Mariposa, Merced, Stanislaus, and Tuolumne. The maps range in content, size, purpose, and historical provenance. Types of maps include the following: water resources, land and parcel, Sanborn fire insurance, irrigation districts (TID/MID), mining, topographical, and railroads. Contact SCUA Librarian Mary Weppler for assistance.

The CSU Stanislaus Library is depository library for federal government and State of California government publications. This includes maps, mineral yearbooks, soil surveys, and other geological publications. Please view our Government Resources Guide for information on how to find and search for government publications at CSU Stanislaus.
