None of Isaac Asimov's stories is called I, Robot. His publisher, Gnome Press, used the title of a short story published in 1939 by Earl and Otto Binder (under the pseudonym Eando Binder) as the title of Asimov's collection. Asimov himself objected to this, while acknowledging the Binders' story as a major influence, but the publishers overruled him.
For details of Asimov's even more famous Foundation trilogy, see Authors: Series.
