This selection of some of Asimov's most enduring and unforgettable stories is read by the author himself. These vintage tales encompass the full range of Asimov's versatility, while displaying his puckish sense of humor.

Un clásico entre los clásicos de la ciencia ficción. Esta historia, que apareció por primera vez en 1976, fue mi exposición más clarividente del desarrollo de los robots. Trataba del deseo de un robot de convertirse en hombre y la forma en que realizaba este deseo, paso a paso. No tenía intención de escribir esta historia cuando la empecé, se escribió sola, y se trazó y entrelazó en la máquina de escribir. Acabó siendo la tercera de mis historias favoritas, entre todas las escritas.
