With Digital Sanborn Maps, you can:
Sanborn Maps were originally published in color, yet the digital maps are displayed in black and white because the digital maps were created by scanning microfilm. Because the original maps were filmed in black and white, the digital images are also in black and white. Due to this source, color images cannot be made available and a maps legend has been specifically created for the black and white images.
While the addresses in the Digital Sanborn Maps, 1857-1970 database are not searchable, you can browse the maps by selecting the state, city, and date. See the screenshot in the "Browsing" window on the left side of this page.
Once you have selected the desired state, city, and date, you may access thumbnails of all of the sheets available from the upper right menu.
1. Click a thumbnail to refresh the page and view the map in the Map Viewer.
2. Navigate back to the top of the page to select a different state, city and/or date.
