First published in the middle of the nineteenth century, following years of research and field study, The Viviparous Quadrupeds of North America (its original title) became the outstanding illustrated work on American mammals of its time and is still considered by many to include the finest animal prints published in North America. The book included many frontier animals never depicted before and helped to increase appreciation of American nature around the world. This edition of Audubon’s classic work has been directly reproduced from an original copy held by the Library of the Natural History Museum, London. All the mammals' current scientific names have been included in the reference section at the back of the book.
