Not a book about the history of the book in America, but about the study of book history and how it is conducted by academics and amateurs alike with extensive notes on the variety of sources worth interrogating such as the archives of publishers, printers, paper makers, literary agents, and retailers, as well as noting the significance of more esoteric evidence such as flyleaf inscriptions and marginalia.  The 80-page essay is followed by a 50-page bibliography.  Paperback.  In very good clean condition.  Cat No 4619
