Over its 150-year history, the American Numismatic Society has published hundreds of monographs. Many of these were scanned by the Google Books project and are now openly accessible through HathiTrust. However, these scanned books provide little functionality for keyword searches or linking to related resources in the archives or numismatic collection of the ANS. As a result, we are publishing fully functional Open Access ebooks through our Digital Library, including EPUB and PDF derivatives for mobile devices.
