Query: A superb literary history of the horror fantasy genre

"Horror of the 20th Century" is a superb literary history of the horror fantasy genre in every media format the 20th century had to offer, including pulp magazine, paperbacks, hardcover novels, comics, radio, television, and the movies (from the early, primitive silent films to the modern, special-effects-laden, big-screen epics of today). The entire spectrum is represented for the short story, the novelette, and the novel. Robert Weinberg's informative, fascinating text is profusely illustrated on every page with full color photographs of wonderful magazine, book, and movie poster art. All of the major authors are represented along with a wealth of biographical information on them and their particular contributions. "Horror of the 20th Century" is a "must" for all horror fantasy buffs, pulp magazine and book collectors, and is a very highly recommended addition to academic and community library collections.
