Digital Sanborn Maps. Library resource containing digital versions of Sanborn fire insurance maps for Oregon for various dates. Compiled for insurance companies, these maps show the location and composition of buildings. They also note potential fire hazards like gas stations, lumber mills, movie theaters, bakeries, and show the location of steep slopes, water mains, and other infrastructure details. Maps for Gresham, Troutdale, and Portland are in this collection, as are maps for the former cities of St. Johns, Albina, and Multnomah (now all part of the city of Portland). Be ready to enter your library card number and PIN; this is a special library resource!
