The Internet Archive has made available every issue of Worlds of IF magazine, which ran from 1952-1974 (when it merged with Galaxy and had a one issue revival in 1986. Many authors had stories published in the magazine, including many award-winning stories and authors, including Robert A. Heinlein’s”The Moon Is a Harsh Mistress” and Harlan Ellison’s “I Have No Mouth and I Must Scream”.
Grandmaster Fredrick Pohl edited the magazine from 1961 and 1969, helping it to rise in prominence and championed new writers. Larry Niven’s first published story, “The Coldest Place”, appeared in the December 1964 issue (the copy of which in the archive is autographed by Niven.)
