A curious entry in the autobiographical material of Asimov's life. If you have no other resources, or your only other resource is the slim "I, Asimov", then you may find more enjoyment in this book. Personally, I found it to be a somewhat disjointed collection of excerpts from the longer autobiography that he wrote (I've read "In Memory Yet Green" and "In Joy Still Felt", which covered 1920-1978). Unfortunately, this is about the best you're going to find these days, especially if you're looking for a digital book. Ye olde paper books are rare and out of print as near as I can tell, so this is the best of what you can find, but don't think you've found the best.
