20,000+ SCIENCE FICTION, FANTASY AND HORROR PAPERBACK BOOKS by (Paperback Collection) [thousands of authors, artists, etc] - 0000

[various places]: [various publishers] [1935-2000 with some later additions], 0000 First editions, first US editions, first UK editions, first paperback editions, plus selected later printings. My personal [20th Century] science fiction, fantasy and horror paperback collection, assembled and continuously upgraded over more than 30 years of collecting. 20,000+ books [with the "+" being several thousand---I stopped actually counting quite some time ago]. Remarkable both for the degree of completeness [US from 1939 and up, starting with the first Pocket Books printing of LOST HORIZON, the LA Bantam Tarzan---three variant copies present---and Shadow titles, etc, etc, and even including several hundred "adult xxx" titles; plus vintage UK from 1935 through 1960 plus selected later titles, plus a sampling of English-Language editions from other countries, etc; with an estimated 95% or so of all non-childrens/juvenile genre-labelled titles included, plus selected childrens/juvenile and non-genre-labelled titles] and for superior condition overall [the majority of books being Near Fine or better copies, save for normal paper aging]. The collection includes hundreds of signed/inscribed copies from dozens of authors/editors/artists and other contributors; plus a number of both US and UK paperbacks in Dust Wrapper; etc. I seriously doubt that there are more than a handful of comparable collections that exist anywhere in the world, and it is the only such collection that I have ever seen offered for sale at any price. Serious inquiries only, please.
