The Harry W. Bass Jr. Library

The Society's 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.
