There are many speculative fiction publications and methods of publication. These include novels, short stories and other short works, poetry, film, television, and artwork, and more recently has begun to include works published entirely online.
Although not a commercial success, it included several significant short stories by distinguished authors, such as Isaac Asimov, Ray Bradbury and Philip K. Dick. The publication has been described by critics as a successor to the tradition of Unknown, a fantasy magazine that ceased publication in 1943. It was noted for printing fantasy with a rational basis such as werewolf stories that included scientific explanations. A selection of stories from Beyond was published in paperback form in 1963, also under the title Beyond.
James Gunn, a historian of science fiction, regarded the magazine as the best of the fantasy magazines launched in the early 1950s, and science fiction encyclopedist Donald H. Tuck contended it printed very good material. Not every critic viewed Beyond as completely successful, however; P. Schuyler Miller, in a 1963 review, commented that the stories were most successful when they did not try to emulate Unknown.
