This was the first bibliography and guide to the American mass market paperback book, and it remains one of the most definitive. The major index is by author, and lists: author, title, publisher, book number, year of publication, and cover price. The title index lists titles and authors only. The publisher index provides a history of that imprint, with addresses, number ranges, and general physical description of the books issued. This is the place that all study of the American paperback must begin.
