The David Rumsey Historical Map Collection is a large private map collection with over 150,000 maps and cartographic items. The collection was created by David Rumsey who, after making his fortune in real estate, focused initially on collecting 18th- and 19th century maps of North and South America, as this era "saw the rise of modern cartography." After 2004 Rumsey expanded the collection to include maps from the 16th though 21st centuries, covering more of the world. In 2008 the collections's website was cited as one of only seven websites with freely available "skillfully compiled carto-bibliographic entries with corresponding early-map images." At that time the site comprised 16,000 digital images. More information...
