Terry Carr edited the first and third series, taking the "TV special" concept and adapting it to paperback marketing.
The serial number given is that of the first printing in the Ace Special series (except for the reissue of Rite of Passage).
Carr had purchased eight more books for the line, which Ace later published after the series was terminated.
The Aldiss volume had been delayed due to issues over Canadian publishing rights, and eventually appeared with the Carr-commissioned Dillon cover.
Terry Carr returned on a freelance basis to edit this series, all of them first novels.
