Ace Science Fiction Specials are three series of science fiction and fantasy books published by Ace Books between 1968 and 1990. Terry Carr edited the first and third series, taking the "TV special" concept and adapting it to paperback marketing. The first series was one of the most influential in the history of science fiction publishing; four of the six novels nominated for 1970 Nebula Awards were from the series.
