Sanborn maps chart the growth and development of more than 12,000 American towns and cities. They are large-scale plans of a city or town, drawn at a scale of 50 feet to an inch and were created to assist fire insurance companies as they assessed the risk associated with insuring a particular property. The maps list street blocks and building numbers.
