A public library is a library that is accessible by the general public and is generally funded from public sources (such as taxes) and operated by civil servants. There are five fundamental characteristics shared by public libraries. The first is that they are generally supported by taxes (usually local, though any level of government can and may contribute); they are governed by a board to serve the public interest; they are open to all and every community member can access the collection; they are entirely voluntary in that no one is ever forced to use the services provided; and public libraries provide basic services without charge.
Public libraries exist in many countries across the world and are often considered an essential part of having an educated and literate population. Public libraries are distinct from research libraries, school libraries, and other special libraries in that their mandate is to serve the general public's information needs (rather than the needs of a particular school, institution, or research population). Public Libraries also provide free services such as preschool story times to encourage early literacy, quiet study and work areas for students and professionals, or book clubs to encourage appreciation of literature in adults. Public libraries typically allow users to take books and other materials off the premises temporarily; they also have non-circulating reference collections and provide computer and Internet access to patrons.
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 (and third largest in the world), 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.
