OldMapsOnline developed out of a love of history and heritage of old maps. The project began as a collaboration between Klokan Technologies GmbH, Switzerland and The Great Britain Historical GIS Project based at the University of Portsmouth, UK thanks to funding from JISC.

The Sanborn Map Company is the oldest mapping company in the United States. Founded in 1866, the company created detailed building maps of cities and towns all across the country, primarily for use by insurance companies. These maps also have been used extensively by local government agencies for over a century in conducting their daily operations efficiently. Approximately 12,000 American cities and towns are chronicled in the company's collection of over one million maps. As a result of its history, the name "Sanborn" has become synonymous with this kind of map. Genealogists, local history buffs, city planners, architects, and countless others have been drawn to the quality of detail found in them.
