Established in 1964, Bookman’s Price Index is an index to rare and antiquarian books offered for sale in the catalogs of 100-200 book dealers in the U.S., Canada, and the British Isles. The number of titles listed in each volume is approximately 15,000; in the course of a year some 50-60,000 books are described. Volumes do not supersede previous volumes. Each volume covers catalogs from the previous 4 to 6 months. Entries Include: Title and author, edition, year published, physical description (size, binding, illustrations); detailed description of the book’s condition including flaws, amount of wear, comment on scarcity; price as listed in catalog; catalog source and number. Included are three appendixes.
