The digital Sanborn collections that various libraries have put online only cover maps published before 1923. Any map published 1923 or after is still in copyright and they are unable to put a digital version online.
This is a collection of more than 3,000 map sheets for the state of Florida. The maps were designed to help fire insurance agents determine the degree of damage to a property and show accurate information to determine risks and establish premiums. They show the size (including color-coding), shape and construction of buildings (brick, adobe, frame, etc), dwellings (including hotels and churches), and other structures such as bridges, docks and barns.
The Sanborn Fire Insurance Maps Online Checklist is a searchable database of the fire insurance maps published by the Sanborn Map Company housed in the collections of the Geography and Map Division. The online checklist is based upon the Library's 1981 publication Fire Insurance Maps in the Library of Congress and will be continually updated to reflect new acquisitions.
