Originally published in 1948, this book contains the text of the Sandars Lectures in Bibliography for the previous year. Carter reflects upon the evolution and method of book collecting from the middle of the nineteenth century until the 1940s, and meditates on what it means to be a book collector, the changing definition of that term, and recent developments in collecting styles. This book will be of value to anyone with an interest in bibliophilism or the history of book collecting.
