Each year, thousands of rare books are sold for hundreds or thousands of dollars each—and often much more—and many of those books are clearly science fiction, fantasy or horror. In 2010, a rare and beautiful 19th-century book, Birds of America by John James Aububon, set a new record by selling for $11.5 million, but a copy of this same book sold last week for a "disappointing" $7.9 million. (Such a bargain!)
So what are the most expensive books in the science fiction, fantasy and horror genre? A careful search of the public records of auction houses and rare book sellers identified the following book sales. To make it more interesting, we've including the top 14 books of 14 different authors that have been sold.
