Two series of companion novels were issued by the publishers. The first series, Galaxy Science Fiction Novels, began in 1950 with Eric Frank Russell's Sinister Barrier; seven titles were released by World Editions, and a further twenty-eight by Guinn's Galaxy Publishing Corporation. The books were initially in digest format but this was changed to a standard paperback format for the last four titles. In 1959 the line was sold to Beacon Books, which produced another 11 volumes. Beacon specialized in softcore pornography, and changed the titles of most of the books they published to be more suggestive. The last title, Sin in Space (originally Outpost Mars), by Cyril Judd (a pseudonym for Cyril Kornbluth and Judith Merril) appeared in 1961. Two years later a second series, Galaxy Magabooks, appeared; each of these consisted of two short novels, both by the same author, published in a single volume. Only three were released; the last, And My Fear Is Great/Baby Is Three by Theodore Sturgeon, appeared in 1964.
