Virtual New York, is a website devoted to the history of New York City and 
its people. Produced by the New Media Lab at the Graduate Center, City 
University of New York, VNY offers resources on New York City's past unavailable 
elsewhere on the Web and, informed by the latest scholarship, new ways to understand 
that history.

Virtual New York's inaugural exhibit "DISASTER!" examines the worst of times 
and how they changed the city.  Currently, 3 exhibits are online:  "The 1863 
Draft Riots", "The Blizzard of 1888" and "Cholera in the Nineteenth Century".
