First opened in 1911, the New York Public Library was created by bringing together a $2.4 million donation from Samuel J. Tilden with the existing Astor and Lexox Libraries in New York City. The site of the Croton Reservoir was chosen for the new library, and its landmark design was conceived by Dr. John Shaw Billings, director of the New York Public Library. When the building opened, it was the largest marble building in the United States, and was home to over 1 million books when it opened.
