The Business & Career Library was a branch of the Brooklyn Public Library (BPL) at 280 Cadman Plaza West in Brooklyn Heights, near Downtown Brooklyn, in New York City. Its history precedes that of the BPL itself. In 1852, prominent citizens established the Brooklyn Athenaeum and Reading Room for the instruction of young men. In 1857, a group of young men established the Brooklyn Mercantile Library Association of the City of Brooklyn, which shared a building with the Athenaeum. The Mercantile Library attempted to be more practical, placing less emphasis on Literature and philosophy. The librarian in charge was Stephen Buttrick Noyes. In 1866, he went to work at the Library of Congress. - Wikipedia
