Sanborn Maps via Library of Congress
This database offers over 35,000 full color maps from communities across the United States. It is very user-friendly and includes color coding. It offers good coverage of New Mexico, as well.
The 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.
