And they were made for just about every city, town and village. The Library of Congress has 50,000 fire insurance maps (700,000 individual sheets) in its collection, most of which were produced by the Sanborn Map Company. The Library has just released a resource guide to help researchers navigate its collection, and explain which maps are available (copyright is an issue with more recent maps). Announcement here.

Meanwhile, Maps Mania has a roundup of other fire insurance maps resources. The Library of Congress has a collection of 50,000 Sanborn atlases, 35,000 of which are available online (collections, navigator). In the United Kingdom, fire insurance maps were produced by Charles E. Goad Ltd.; Goad maps are available via the British Library and the National Library of Scotland.

Fire insurance maps are an invaluable resource for historical researchers: they’re extremely detailed snapshots of the built environment of virtually every city and town, and there are usually several such snapshots (I’ve seen at least three for my little village, for example), so you can chart a town’s growth over time at a level of detail an OS, quad or topo map can’t match.

Known for its detailed fire insurance maps during the late 19th and early/mid 20th centuries—a treasure trove for historians—Sanborn has since diversified into a geospatial company, though fire insurance maps are still one of their business lines.
