The New-York Historical Society, the NYU Fales Library and Special Collections and DLTS created a digital library of primary source material from the American Revolutionary War, documenting events in the New York City region. The material includes all of the items in the Richard Maass Collection at Fales, one of the more significant collections of material documenting activities during America’s Revolutionary War in New York State, the William Alexander manuscripts from the New-York Historical Society, and the Robert Erskine/Simeon De Witt collection of survey maps from New-York Historical Society. This digital library was developed through funding from the Institute of Museum and Library Services.
