National Geographic's Map Machine

Do you like maps? Drawn from the map collection at the U.S. Library of Congress, these authentic historical maps reflect the world that existed when they were created. In some cases California is an island, New York City is a mid-sized city of under one million people, and railways snake westward across the opening U.S. The date in parentheses after the map title is the actual year of creation. Try to find the City in the New York City map (1639).
