ProQuest’s Sanborn Maps Geo Edition (1867-1970) is a geo-referenced version of the Sanborn collection for the US, already purchased and available at http://purl.lib.uiowa.edu/sanborn.

The Geo Edition provides digital access to thousands of large-scale maps of American towns and cities, searchable by address and GPS coordinates. These maps can be saved in either JPEG or Geotiff format (the latter retains its georeferencing and can be added to a GIS program such as ArcGIS).

For help using this product, see MSU’s handy guide at http://libguides.lib.msu.edu/content.php?pid=101767&sid=1054316.
