Don't miss this favorite tradition, Discovery Day on Sunday, March 8th. Discovery Day gives ticketed visitors the opportunity to bring in their own rare books, manuscripts, maps, etc. (up to 5 items) to be examined by our panel of exhibitors who will offer expert advice and appraisals. So plan to bring in your treasures - we want to see them! The New York Antiquarian Book Fair is officially sanctioned by the Antiquarian Booksellers’ Association of America and the International League of Antiquarian Booksellers and produced and managed by Sanford L. Smith + Associates.
