Sanborn Maps :

For charting the block-by-block growth of Fresno County towns and cities, the Sanborn fire insurance maps display information found nowhere else. Utility lines, property dimensions, building specifications/modifications, and much other historically useful data are available on these maps. See a list of the Sanborn maps covering Fresno County. The Room has copies of three original Sanborn atlases for Fresno proper, and microfilm copies of atlas plates for Fresno and other county cities and towns.
