David Rumsey Maps
One of the premier digitized historical map collections, offering high-resolution scans, many of them georeferenced, on the Luna platform. Partial Luna and IIIF APIs exist, but the practical route is the site's own search interface, which we link to. A first stop when you need a high-quality scan of an old map.
