Infinity Science Fiction was an American science fiction magazine, edited by Larry T. Shaw, and published by Royal Publications. The first issue, which appeared in November 1955, included Arthur C. Clarke's "The Star", a story about a planet destroyed by a nova (an exploding star) that turns out to have been the Star of Bethlehem; it won the Hugo Award for that year. Shaw obtained stories from some of the leading writers of the day, including Brian Aldiss, Isaac Asimov, and Robert Sheckley, but the material was of variable quality. In 1958 Irwin Stein, the owner of Royal Publications, decided to shut down Infinity; the last issue was dated November 1958.
The title was revived a decade later by Stein's publishing house, Lancer Books, as a paperback anthology series. Five volumes were published between 1970 and 1973, edited by Robert Hoskins; a sixth was prepared but withdrawn after Lancer ran into financial problems at the end of 1973.
