Trade paperback published by Ballentine, first edition 1976. Not a price guide but a compendium, look through it to find all the releases you might not even know exist. American and UK pressings are what you will find but if a title was released it should be in here somewhere.This copy has tight pages but some cover wear so selling it for notably less than others being offered. Knowledge gained for collectors or dealers either one more than worth the price, and fun as well. Photo of actual copy being offered is shown.
