Science Fiction Quarterly

Science Fiction Quarterly (SFQ) was one of three SF magazines edited by Charles D. Hornig in the late 1930s-early 1940s, the other two being Science Fiction and Future Fiction. All three were published by Louis Silberkleit.

The editorial policy of SFQ called for a complete novel in each issue, giving it an advantage over other magazines of the time.

The first series began publication Summer, 1940, and ended with a Spring, 1943, issue. The second series ran from May, 1951, until February, 1958. The two series had a total run of 38 issues.

Robert W. Lowndes succeeded Hornig as editor in 1941.

Members of the Futurians, the New York SF club of which Lowndes was a member, contributed short fiction to the magazine; and Hannes Bok, also a Futurian, contributed artwork.

The second series of the magazine was known for its nonfiction rather than its fiction. Authors who had nonfiction articles published included Isaac Asimov, L. Sprague de Camp, James Blish, Robert Madle, and Sam Moskowitz.

SFQ is considered to have been the last of the SF pulp magazines.

There was also a British edition, also published in two separate series, first in the 1940s and then again in the 1950s.
