The New York Public Library (NYPL) is a public library system in New York City. With nearly 53 million items, the New York Public Library is the second largest public library in the United States, behind only the Library of Congress. It is an independently managed, nonprofit corporation operating with both private and public financing. The library has branches in the boroughs of Manhattan, The Bronx and Staten Island and it has affiliations with academic and professional libraries in the metropolitan area of New York State. The City of New York's other two boroughs, Brooklyn and Queens, are served by the Brooklyn Public Library and the Queens Borough Public Library, respectively. The branch libraries are open to the general public and consist of research libraries and circulating libraries.
The library originated in the 19th century, and its founding and roots are the amalgamation of grass-roots libraries, social libraries of bibliophiles and the wealthy, and from philanthropy of the wealthiest Americans of their age.
