The New York Public Library was created in 1895 with the consolidation of the private libraries of John Jacob Astor and James Lenox with the Samuel Jones Tilden Trust. The Library provides free and open access to its physical and electronic collections and information, as well as to its services. It comprises four research centers - The Humanities and Social Sciences Library; The New York Public Library for the Performing Arts; the Schomburg Center for Research in Black Culture; and the Science, Industry and Business Library - and 86 Branch Libraries in Manhattan, Staten Island, and the Bronx. Research and circulating collections combined total more than 50 million items. In addition, each year the Library presents thousands of exhibitions and public programs, which include classes in technology, literacy, and English as a second language. The New York Public Library serves over 16 million patrons who come through its doors annually and another 26 million users internationally, who access collections and services through its website, www.nypl.org.
