Ballantine's Classic Library of Science Fiction
Ballantine's Classic Library of Science Fiction is a series of speculative fiction collections originally published in the 1970s and 1980s purporting to gather together the career-best short works of a selection of authors then prominent in the field. The series was conceived and published in paperback by Ballantine Books (later Del Rey Books), though most of the early volumes also had initial hardcover editions issued by Doubleday's Science Fiction Book Club preceding the Ballantine/Del Rey paperback editions.

Title variations
The series title varied over time; with volumes published in 1974 issued without an overall title, volumes published from 1975 into 1977 called "Ballantine's Classic Library of Science Fiction," or "our Classic Library of Science Fiction" in the instance of a few Del Rey printings, and volumes published from November 1975 onward  called "The Critically Acclaimed Series of Classic Science Fiction." Most volumes bore the words "Classic Science Fiction" on the above the title of the individual volume.
