The so-called “Second Foundation Trilogy” is a significant development in the world of Asimov’s fiction. Inasmuch as Asimov wasn’t personally involved in (or even aware of) this work, I really can’t in good conscience count them as official books—I’ve stretched things badly enough by counting Harlan Ellison’s I, Robot: The Illustrated Screenplay.
(I cannot help but think of the analogy to the works of the late Dr. Seuss. A huge body of subsidiary Seuss literature has appeared since Geisel’s death. This material is presumably authorized by his estate but definitely not up to the usual Seuss standard of quality, thereby cheapening the name. There are legitimate concerns regarding this scenario playing out with Asimov.)
But the books were requested by Janet Asimov and Ralph Vicinanza, whom Benford calls “the Asimov estate’s representative,” and they are written by three top-flight science fiction authors whose work I enjoy and respect, so I have reviewed them.
The three books in the “second trilogy” are:
Foundation’s Fear (1997) by Gregory Benford
Foundation and Chaos (1998) by Greg Bear
Foundation’s Triumph (1999) by David Brin
Similarly, I have reviewed the festschrift edited by Martin Greenberg honoring Asimov on the occasion of the fiftieth anniversary of his first sale, namely:
There are also a number of books which have been written about Asimov or his works over the years which I have reviewed. Some of them are:
Trillion Year Spree: The History of Science Fiction (1986) by Brian W. Aldiss and David Wingrove
Asimov’s Foundation Trilogy and Other Works: Notes (1977) by L. David Allen
Isaac Asimov: The Foundations of Science Fiction (1982) by James Gunn
Isaac Asimov (1982) by Jean Fiedler and Jim Mele
Isaac Asimov (1974) edited by Joseph D. Olander and Martin Harry Greenberg
The Science Fiction of Isaac Asimov (1977) by Joseph F. Patrouch, Jr.
Isaac Asimov (1991) by William F. Touponce
Asimov: The Unauthorized Life (1994) by Michael White
Other non-Asimov titles will be added as I read them.
