Science-Fiction Plus (with a lower-case subtitle: preview of the future) was a science fiction magazine published from Philadelphia by Gernsback Publications, Inc. in 1952-53. With a large bedsheet-size format, it began as a monthly but switched to bi-monthly with the June 1953 issue.
Edited by Hugo Gernsback and Sam Moskowitz, the 68-page magazine sold for 35 cents and ran for eight issues, from November 1952 to December 1953. Not intended as a pulp magazine, it began as a slick printed on quality paper with glossy covers. However, in the course of the run, the paper switched from slick to "book paper".
The lineup of writers included Robert Bloch, Philip José Farmer, Murray Leinster, Chad Oliver. Clifford D. Simak and James H. Schmitz. It featured the first published story by Anne McCaffrey. Cover illustrations were by Frank R. Paul and Alex Schomburg, with interior illustrations by Muneef Alwan, Seymour Augenbraun, Paul Cooper, Virgil Finlay, Charles Hornstein, Jay Landau, Tom O'Reilly, Frank R. Paul and others.
The first issue had novelettes by Gernsback, Farmer and Donald Howard Menzel, with short stories by John Scott Campbell, Gernsback (as Greno Gashbuck) and Otto Binder, book reviews by Moskowitz and a variety of essays.
