Space Science Fiction Magazine was a US science fiction magazine published by Republic Features Syndicate, Inc. as part of a package of radio shows and related genre magazines. It was edited by Michael Avallone, though the masthead listed Lyle Kenyon Engel as editor instead. Two issues appeared, both in 1957. It published short stories by well-known writers, including Arthur C. Clarke and Jack Vance, but it was not successful, and the magazine ceased publication late in 1957. Publication history and bibliographic data Science fiction was one of the staple genres of American pulp magazine publishing, beginning in 1926 with Amazing Stories. A brief boom in the late 1930s was cut short by World War II, but the field expanded again in the late 1940s. By 1957 the boom had reached its height; 24 science fiction magazines published at least one issue that year. One of the most prominent of these magazines, Galaxy Science Fiction, had a successful association with two radio shows, Dimension X and X Minus One. This sparked imitators, and during 1956 Lyle Kenyon Engel of Republic Features Syndicate persuaded an investor to finance a package of two radio shows and four magazines. The shows were American Agent, a spy drama, and The Frightened, to be narrated by Boris Karloff. The magazine package included a spy magazine and a horror magazine to tie in with the radio shows, and two additional titles: Private Investigator Detective Magazine and Space Science Fiction Magazine. Private Investigator's first issue was published in 1956, but problems with the radio schedules delayed the launch of the other magazines until 1957. Space SF's first issue was dated Spring 1957, although its masthead indicated that it would be a bimonthly. It was published by Republic Features Syndicate, Inc., of New York, and edited by Michael Avallone, who was not credited on the masthead, since he was also contributing material to some of the four magazines, both under his own name and under pseudonyms. The second issue was dated August 1957; this proved to be the final issue, as shortly thereafter Republic Features Syndicate went out of business. The liquidation of American News Company earlier that year, a major distributor, had led to the extinction of many magazines, as they had to scramble to find new distributors, but it is not known if Space SF was one of the victims. Both issues were digest-sized, with 132 pages,
