This first volume of The Science Fiction Hall of Fame (though actually the word "The" is not part of the bibliographic title, on the title page), was a recognition by the Science Fiction Writers of America, as it was known then, formed in the mid-1960s, of all the stories published before the advent of the Nebula Awards, first awarded in 1966 for works published in 1965. Silverberg's introduction describes the process of conducting this survey of members for works up to 15,000 words published in 1964 or earlier. He also discusses some editorial decisions, to produce an anthology with no more than one story per author.
Page numbers displayed here are taken from the SF Book Club edition, which may be slightly different than those in the original 1970 Doubleday edition.
