used it (and its later incarnations) to publish his own "spiritual technology," as well as his ideas about business administration, literacy, and drug rehabilitation. Hubbard returned to the field of Science Fiction writing in 1982 with the publication of Battlefield Earth, followed by the Mission Earth "dekalogy," a ten-volume series, most of which was published posthumously. Output and reception Hubbard produced more than 250 published works of fiction in his writing career. At his peak, he wrote “over 100,000 words a month.” He is remembered for his “prodigious output" and the "amazing speed at which he could produce copy.” He used a special electric IBM typewriter with extra keys for common words like ‘and’, ‘the’, and ‘but.’ Scientology's publishing arm has translated his work into seventy-two languages. His fiction and non-fiction books have sold millions of copies, and Hubbard holds four Guinness World Records for “Most Published Works by One Author”, “Most Audio Books Published for One Author”, “Most Translated Author in the World”, and "Most Translated Author, Same Book" (The Way to Happiness). Criticism of Hubbard's fiction is mixed. Georges T. Dodds, columnist for WARP, newsletter/fanzine of the Montreal Science Fiction and Fantasy association writes, "much of [Hubbard's]science fiction and fantasy is quite entertaining, and in most cases as good or better than much of the pulp literature of the era." A reviewer for Publishers Weekly emphasizes "Hubbard's ability to pack an epic into relatively few pages -- this is indeed golden science fiction from the Golden Age.". The Encyclopedia of Science Fiction maintains that science fiction "was clearly not Hubbard's forte, and most of his work in the genre reads as tendentious or laboured or both. As a writer of fantasy, however, [Hubbard] wrote with an occasionally pixillated fervour that is still pleasing, and sometimes reminiscent of the screwball comedies popular in the 1930s cinema." Encyclopedia of Science Fiction says about Hubbard's last foray into the genre of science fiction: "Battlefield Earth: A Saga of the Year 3000 (1982), [is] an enormously long space opera composed in an idiom that seemed embarrassingly archaic. This was followed by the Mission Earth 'dekalogy,' a ten-volume sequence whose farcical over-egging of a seriously thin narrative thread fails to disguise a tale that would have been more at home in the dawn of the Pulp magazines, though its length would not have been tolerated."
