ANS headquarters is comprised of several distinct departments that work together to fulfill the Society's mission:

Archives: The mission of the Archives is to serve as a centralized resource for historical information about the Society. The ANS Archives collects, preserves, and makes accessible the historical records of the Society, uses its records to promote to key audiences the Society's heritage, and supports the Society's staff in their roles as scholars and administrators.

Curatorial: The collections of the ANS are supported by the work of a senior collections manager and by full, associate, visiting, and assistant curators specializing in all aspects of numismatics. Requests to use the collection for numismatic research must be submitted in writing to the collections manager in advance of your visit.

Library: The Harry W. Bass Jr. Library, which houses one of the world's most comprehensive collections of numismatic literature, presently numbers some 100,000 items. These include books, periodicals, manuscripts, photographs, pamphlets, auction catalogs, and microforms, all of which are cataloged. In addition to numismatic works, the Library includes a strong reference collection and a wide selection of non-numismatic periodicals in the areas of archaeology, art history, economic history and other disciplines.

Membership: The ANS is a privately funded 501(c)(3) non-profit organization, supported by membership fees and contributions, sales of publications, and foundation, corporate and government support. Learn how to become an individual or institutional member.

Photography: The ANS employs one full-time photographer and one assistant photographer to assist in the documentation of the ANS's permanent collection as well as its events and exhibits. Authors of articles, books, and other media (both print and digital) and producers of content who wish to use images produced by the American Numismatic Society (ANS) must request permission to use those images. Requests for new photography are also welcome, and are subject to a photography fee.

Publications: The ANS has an active publication program that began in 1866 with the first numismatic periodical in the United States, and continues today with a variety of print and digital publications on all aspects of numismatics.
