I am a fan of Isaac Asimov. It's hard to get any more of his books as most are out of print. That's why I was delighted to find this hardcover book during one of the Pay Less Book Warehouse Sale.
There are 24 short stories in this book. At the end of each story there is a short but sometimes long commentary from the author on how each of the story got written, what was the original title and some personal opinion on each story.
Some of the stories could be rather eerie too like the story of "Each An Explorer", about the possibility of plant/vegetation developed high intelligence till it can control human.
