The New-York Historical Society, one of America's preeminent cultural institutions, is dedicated to fostering research and presenting history and art exhibitions and public programs that reveal the dynamism of history and its influence on the world of today. Founded in 1804, New-York Historical has a mission to explore the richly layered history of New York City and State and the country, and to serve as a national forum for the discussion of issues surrounding the making and meaning of history. New-York Historical is also home to the Patricia D. Klingenstein Library, one of the oldest, most distinguished libraries in the nation—and one of only 20 in the United States qualified to be a member of the Independent Research Libraries Association—which contains more than three million books, pamphlets, maps, atlases, newspapers, broadsides, music sheets, manuscripts, prints, photographs, and architectural drawings.
