Orbit 

Orbit is a long-running series of anthologies of new science fiction edited by Damon Knight; often featuring work by such writers as Gene Wolfe, Joanna Russ, R. A. Lafferty & Kate Wilhelm, who was married to Knight. The anthologies tended toward the avant-garde, but by no means exclusively; occasionally the volumes would feature some nonfictional critical writing or humorous anecdote-gathering by Knight. Inspired by Frederik Pohl's Star Science Fiction series, & in its turn an influence on Harlan Ellison's Dangerous Visions volumes & many others, it ran for over a decade & eighteen volumes, including a double-volume but excluding a "Best-of" collection which covered 1966-76.
