The Nebula Awards are voted on, and presented by, active members of the Science Fiction and Fantasy Writers of America, Inc. (or SWFA)—and the Grand Master Award is given by the SWFA to a living author for a lifetime's achievement in science fiction and/or fantasy.

Frederik Pohl, one of the world's finest SF authors and editors, has been authorized to edit an anthology in three large-format volumes featuring substantial selections of the work of all the first fifteen Grand Masters. These are the seminal writers within the modern SF field, those whose works are of dominant importance and lasting influence.

Volume Two, presenting the second five writers to receive the award, offers fiction by Andre Norton, Arthur C. Clarke, Isaac Asimov, Alfred Bester, and Ray Bradbury.
