Sanborn Maps

Sanborn Fire Maps
The Sanborn Maps were originally created for assessing fire insurance liability in urbanized areas in the United States. Our collection includes over 40,000 detailed maps of Ohio cities drawn between 1882 and 1962. Each map includes detailed information regarding town and building information. Although these maps were originally published in color, our collection is digitized from microfilm and is in black and white.

You can use this collection to:

  • Locate the residences and workplaces of ancestors.
  • Understand the significance and historical evolution of buildings.
  • See what your town looked like in the past and how it has changed over time.
