"New Worlds in Old Books is about an adventure of a lifetime - how two young women from New York introduced whole new worlds of collecting to the antiquarian book field. This work is based on the authors' experience and holdings for over a half century and offers a fresh and unique insight in collecting. New Worlds reflects their fascination and reveals the astonishing fact that many early volumes foreshadowed the technology, medicine, sciences, political philosophy, and social practices of today."--BOOK JACKET. "In New Worlds in Old Books we discover old titles that have eye-witness accounts of great events, problems of minorities, Satanic demonology, the lure of first editions, and unusual ownerships."--Jacket.
