The David Rumsey Map Collection contains more than 150,000 maps. The collection focuses on rare 16th through 21st century maps of North and South America, as well as maps of the World, Asia, Africa, Europe, and Oceania. The collection includes atlases, wall maps, globes, school geographies, pocket maps, books of exploration, maritime charts, and a variety of cartographic materials including pocket, wall, children's, and manuscript maps. Items range in date from about 1550 to the present.

The physical map collection is housed in the David Rumsey Map Center at the Stanford University Library. Over 123,00 items in the collection are online, with new material added regularly. The collection website provides a number of tools, including Luna Viewer, the collection database, Georeferencer v4, which allows users to overlay historic maps on modern maps or other historic maps, and MapRank search, which enables geographical searching of the collection by map location and coverage, in a Google Map window.
