Founded in 1867, the Sanborn Map and Publishing Company was the primary American publisher of fire insurance maps for nearly 100 years. The Fire Insurance Maps aided insurance agents in estimating fire insurance liabilities in urban areas. The maps provide a detailed account of urban development and change in communities during the early twentieth century. Sanborn maps are large-scale (1:600) and depict street layouts, building footprints, building materials, utility lines, street names, street and sidewalk widths, property boundaries, building use, and house and block numbers. Sanborn produced Indiana maps between 1883 and 1966. Currently, all maps produced by 1925 are in the public domain.
