Foundation is the second-greatest science fiction series of all time.

(The greatest, of course, is Dune.) In 1973, the BBC recorded an 8-episode radio series of Asimov‘s Foundation Trilogy. The show is now in the public domain and available for download at the Internet Archive. It’s well done. When I read Foundation I failed to continue past the original trilogy into the later work. This show has encouraged me to revisit the books.
