New Sanborn Maps
Sanborn Maps from Library of Congress. The Library of Congress has begun making the maps accessible on its website in a sheet-by-sheet format that will allow printing. By year’s end, more than 100,000 maps published prior to 1900 will be available online. They will join more than 1,200 pre- and post- 1900 maps that were previously scanned and made available online.
