Sanborn Fire Insurance Maps Online Checklist "provides 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. The online checklist also contains links to existing digital images from our collection and will be updated as new images are added."
