Sanborn Fire Insurance Maps  

The Library of Congress has placed online nearly 25,000 Sanborn Fire Insurance Maps, which depict the structure and use of buildings in U.S. cities and towns. Maps will be added monthly until 2020, for a total of approximately 500,000.

The Sanborn Fire Insurance Maps are a valuable resource for genealogists, historians, urban planners, teachers or anyone with a personal connection to a community, street or building.  The maps depict more than 12,000 American towns and cities.  They show the size, shape and construction materials of dwellings, commercial buildings, factories and other structures.  They indicate both the names and width of streets and show property boundaries and how individual buildings were used.  House and block numbers are identified.  They also show the location of water mains, fire alarm boxes, and fire hydrants. 

The Library’s Geography and Map Division is among the world’s largest map collections, holding some six million cartographic items in various languages dating from the 14th century to the present.  Some of its most important collections are available online at loc.gov/maps/collections/.  Further information about the Geography and Map Division can be found at loc.gov/rr/geogmap/.
