Notes: Edited by Patricia S. Warrick and Martin H. Greenberg. (The copyright page states 'Edited by Dan Seiters', who was the publicity manager for Southern Illinois University Press). There is an introduction to every shortfiction, presumably written by Warrick and Greenberg (the same holds for the introduction to the book). 'Impostor' is titled 'Imposter' throughout the book, and it's 'Electric Ant' on the contents page and the page headings of the story but 'The Electric Ant' on the introductory page (p. 213) for the story. Richard Hendel is credited for the design on the copyright page.
