Twilight World

This was not published as a collection. It's actually a fix-up of two earlier stories (the first in collaboration with F. N. Waldrop who is not credited in the book) with a third newly written for this novelisation.

• Subtitled "A Science Fiction Novel of Tomorrow's Children"
• Assembles three shorter works to form a "novel"
• "Prologue" is the same as "Tomorrow's Children" by Anderson and F. N. Waldrop. Waldrop is not given credit in this book.
• Artist not credited.
• Gutter code B-49 on page 181.
• Month of publication from Currey. He presumes this to be simultaneous with the SFBC edition, which has the same gutter code on the same page, and likely both were from the same print run.
