"Gold" is, according to the book's cover, the final science fiction collection from Isaac Asimov. One of the genre's most revered figures, Asimov died in 1992. "Gold" contains both short stories and a bunch of short essays. While the material in "Gold" does not quite reach the level of Asimov's best work, the book is still worth reading.
Part One of "Gold" sandwiches 13 short stories in between two longer tales of about 40 pages each. I found most of the shorter tales to be fairly forgettable, but the longer ones are fine pieces. The first of the two longer tales, "Cal," is a cleverly written tale of a robot who wants to be a writer. This is a moving tale which effectively returns to one of Asimov's great themes (the place of robots in human-dominated society). The second of the longer tales, "Gold," is a compelling story of a science fiction writer who hires a director to make a "compu-drama" out of one of his books. This thoughtful story is an interesting commentary on two things: (1) the relationship of science fiction to canonical "high" literature, and (2) the relationship of science fiction books to science fiction in other media.
The short essays are a mixed bag, but the best of them are delightful. They are full of amusing and enlightening anecdotes, often about other classic SF writers of Asimov's generation. Some of Asimov's essay topics include women and SF, religion and SF, the SF short-short story, plagiarism, and the background to the names of some of his fictional characters. Asimov's essay on book reviewing is particularly interesting; I think that everyone who participates in the Amazon review program should read this essay (entitled "Book Reviews," it's on pages 369-374 of the paperback edition).
Finally, a personal note. Isaac Asimov was one of my childhood icons, and many of his classic stories had a profound influence on me. I will also never forget the opportunity I had to hear him speak in person at a New York City convention: he was as delightful and charming in person as he is in print. If you are a fan of Asimov or of that great generation of SF writers in general, don't miss "Gold."
