Note: Essay starts: "In the spring of 1967, I received an interesting request." Essay finishes: "The nicest result of the publication of the story, by the way, was that Abbottempo published it in each of their eight editions. They sent me a boxed collection of each set in 1) English, 2) French, 3) Spanish, 4) German, 5) Italian, 6) Japanese, 7) Greek, and 8) Turkish, and the set remains one of the more interesting oddities of my personal library of Asimoviana." "First appearance – Abbottempo, Book 4, 1967. Copyright, 1968, by Isaac Asimov."
