First published in 1980 under the title The Arbor House Treasury of Modern Science Fiction, this Genre Anthology was edited by Robert Silverberg and Martin H. Greenberg. It was republished under the title Great Science Fiction of the 20th Century in 1987 under the Avenel Books imprint of William Morrow & Company (who would complete their purchase of Arbor House in 1988).
Inspired by The Best Of Science Fiction by Groff Conklin and Adventures In Time And Space by editors Raymond J Healy and J Francis Mc Comas (both published in 1946), the Great Science Fiction of the 20th Century anthology attempts to be a Spiritual Successor, collecting stories only between the years of 1947 and 1976. The majority of these stories are Novelette or longer.

Tropes appearing in this anthology:
- Doorstopper: This Anthology has over 700 pages because most of the thirty-nine stories are actually short novels, classified as Novelettes or Novellas.
- Genre Anthology: Science Fiction stories only, ones with the best potential to shape the way people would view the future and inspire people to greater heights of creativity.
- Orwellian Retcon: William Morrow & Company had The Arbor House Treasury of Modern Science Fiction reprinted under their Avenel Books imprint with the name Great Science Fiction of the 20th Century to avoid the confusion of listing multiple publisher names.
