High Quality Content by WIKIPEDIA articles! Orbit was a long-running series of anthologies of new fiction edited by Damon Knight, often featuring work by such writers as Gene Wolfe, Joanna Russ, R. A. Lafferty, and Kate Wilhelm, who was married to Knight. The anthologies tended toward the avant-garde edge of science fiction, but by no means exclusively; occasionally the volumes would feature some nonfiction critical writing or humorous anecdotes by Knight. Inspired by Frederik Pohl`s Star Science Fiction series, and in its turn an influence on Harlan Ellison`s Dangerous Visions volumes and many others, it ran for over a decade and twenty-one volumes, not including a "Best-of" collection which covered the years 1966-1976.
