Library of Congress Online ChecklistThe Library of Congress has digitized and compiled a searchable online checklist of Sanborn fire insurance maps. The online checklist is based upon the Library's 1981 publication on 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 its collection and will be updated as new images are added.
The Sanborn maps are arranged by state, then city and release data. Currently there are over 25,000 sheets from over 3000 city sets online in the following states: AK, AL, AZ, CA, CO, CT, DC, DE, GA, ID, IL, IN, KY, LA, MA, MD, ME, MI, MO, MS, NC, ND, NE, NH, NJ, NV, OH, OK, PA, SD, TX, VA, VT, WY and Canada, Mexico, Cuba sugar warehouses, and U.S. whiskey warehouses.
