THE EARLY ASIMOV
by Isaac Asimov
The title is only half the story. This is the interstitial early Asimov — less politely, what wasn't good enough to reprint elsewhere. It's a nostalgic journey through the pulps of the '40's with all Asimov's themes from positronic robots to mathematical psychology to galactic empire putting in an appearance, laced with fond reminiscences of editor John Campbell who presided over SF's golden age and with exhaustive reports on each story clown to the last penny it brought in the marketplace.
