The American Antiquarian Society (AAS), located in Worcester, Massachusetts, is both a learned society and a national research library of pre-twentieth-century American history and culture. Founded in 1812, it is the oldest historical society in the United States with a national focus. Its main building, known as Antiquarian Hall, is a U.S. National Historic Landmark in recognition of this legacy. The mission of the AAS is to collect, preserve and make available for study all printed records of what is now known as the United States of America. This includes materials from the first European settlement through the year 1876.The AAS offers programs for professional scholars, pre-collegiate, undergraduate and graduate students, educators, professional artists, writers, genealogists, and the general public.The collections of the AAS contain over four million books, pamphlets, newspapers, periodicals, graphic arts materials and manuscripts. The Society is estimated to hold copies of two-thirds of the total books known to have been printed in what is now the United States from the establishment of the first press in 1640 through the year 1820; many of these volumes are exceedingly rare and a number of them are unique. Historic materials from all fifty U.S. states, most of Canada and the British West Indies are included in the AAS repository. One of the more famous volumes held by the Society is a copy of the first book printed in America, the Bay Psalm Book. AAS has one of the largest collections of newspapers printed in America through 1876, with more than two million issues in its collection. Its collections contain the first American women's magazine edited by a woman, The Humming Bird, or Herald of Taste.
