Why Historical Maps Still Matter So Much, Even Today

Mega-collector David Rumsey explains how maps are an "archive of information."

With 150,000 or so old print maps to his name, David Rumsey has earned his reputed place among the world's "finest private collectors." But the 69-year-old San Francisco collector doesn't have any intention of resting on his cartographic laurels. He continues to expand his personal trove as well as the digitized sub-collection he makes open to the public online — some 38,000 strong, and growing.

"I'm pretty old for a geek map guy," he says. "But I stay young by embracing new technologies all the time."
