A third Silverberg Arbor House anthology followed in 1983, a companion to the earlier volumes with an expanded scope: "to trace the evolution of today's science fiction by linking the earlier 'mainstream' s-f literature to the best of the pulp-magazine work of modern writers." The lower boundary is set at Edgar Allan Poe; the upper boundary is the year of the book's publication.
As with Silverberg's first Arbor House anthology, there is some overlap with his earlier Alpha anthologies; 12 of the stories here appeared earlier in those nine volumes.
