The Jeffersonian Cyclopedia, 1st Patrons' Centennial Edition, edited by John P. Foley, July 31st 1900 is a reference book on all of the works of Thomas Jefferson in an encyclopedia format. Little did Foley know that this book would be his last contribution to mankind, having died the same year it was published.
See, Preface for Foley's discussion on this book. We included an image of it for your convenience. This book is very good condition for its age (122 years), though the spine has seen better days, so we rated it Good+ and priced it accordingly as an exceedingly rare book.
