Sanborn Fire Insurance

Sanborn Fire Insurance Maps are highly detailed city plans providing researchers with a wealth of information about urban change in American cities. These maps were originally produced between 1867 and 1970 for the purpose of assessing risk and cost of insurance. The highly detailed plans were drawn at a scale of 50 feet/inch (1:600), printed in color, and record detailed information about streets, businesses, residences, building materials, and utilities.

ProQuest has taken the Chadwyck-Healey Sanborn Fire Insurance Maps microfilm collection, some 660,000 maps, and enhanced and digitized the maps. Since the maps have been digitized from the microfilm version, the ProQuest product is in black & white rather than in color as were the original paper maps. The ProQuest interface to Sanborn Maps provides the ability to easily manipulate the maps, magnify and zoom in on specific sections, and compare maps from different years.
