Map collector David Rumsey has agreed to donate some 150,000 maps of the Americas, most of which were drawn between 1700 and 1925, to the Stanford University Libraries. The collection includes physical maps as well as digital images. The physical maps will be housed in the University Libraries' Special Collections and the digital files will be preserved in Stanford's digital preservation archive.
Digital images from Rumsey's collection can be viewed at the David Rumsey Map Collection. The collection includes such gems as a map showing the first depiction of the Rocky Mountains found folded into a first edition of Lewis and Clark's 1814 travel book chronicling their trek across the American West and an 1839 atlas showing Texas as an independent republic. Many of the maps from the Rumsey collection are already cataloged, and can be found by searching for David Rumsey maps in the Stanford Libraries' Web environment.
