American Antiquarian Society

The American Antiquarian Society (AAS) cultivates a deeper understanding of the American past, grounded in its ever-growing collection of printed and manuscript sources. The Society fosters a broad community of inquiry through inclusive programs and generous support of scholarship.

A national research library and learned society founded in 1812 by Revolutionary War patriot and printer Isaiah Thomas, AAS is located in Worcester, Massachusetts. The AAS library today houses the largest and most accessible collection of books, pamphlets, broadsides, newspapers, periodicals, children's literature, music, and graphic arts material printed before the twentieth century in what is now the United States, as well as manuscripts and a substantial collection of secondary texts, bibliographies, and digital resources and reference works. AAS was presented with the 2013 National Humanities Medal by President Obama in a ceremony at the White House.
