The Thunder Child writes “Isaac Asimov wrote hundreds of essays, many of them for the Magazine of Fantasy and Science Fiction. These were collected into anthologies, and we have put together a 121-page, annoted index, in a free PDF, which you may download by going here. It lists every name Asimov ever mentioned, his description of them, and their birth and death dates.
Then, have a bit of fun with our “To Be Sure” contest. “To be sure” was one of Asimov’s favorite phrases, and if you’ve got a collection of his essay anthologies, and care to play the game, there’s prizes at the end of it. See more details here“
