Isaac Asimov (1920-1992) was considered one of the "Big Three" science fiction writers, along with Robert A. Heinlein and Arthur C. Clarke. In this collection are six books from this series, as well as Greg Bear's Foundation and Chaos (1998), the second book of the Second Foundation trilogy, which was written after Asimov's death by three authors and authorised by the Asimov estate.
