The Sanborn Map Company, the best known of the U.S. fire-insurance map producers, has made maps since 1867. The fire insurance maps produced by Sanborn show building footprints, building material, height or number of stories, building use, lot lines, road widths and water facilities. The maps also show street names and property boundaries of the time. This collection of maps is historically significant as it is sometimes the best detailed map of a town or city dating from the mid 1800s. The Penn State University Libraries' Center for Maps and Geospatial Information has a near complete collection of Sanborn Fire Insurance maps for the state of Pennsylvania. The print collection can currently be accessed by contacting the Center staff.
