I'm the first to review this book. Hope this will be helpful to would be buyers.
This book is not very interesting for an advanced SF reader. Why?
Writers featured in this book are Asimov, Bester, Bradbury, Clarke and Norton. Good and popular writers, but their work is still very easy to come by. Want stories of Asimov? Buy his two-volume collection. Same for Bradbury, who has a very nice one-volume collection, and for Clarke and Bester. The stories in this anthology will tell you that these writers deserve to have a single-author collection on your bookshelves. Why buy stories you already own?
For starters then. Buy this book. Some stories in here are classics, others are mere filler. They point out to you their writers' vision. Still, it's your decision. The truth: There are better anthologies out there.
Whatever your decision, do check out the first item in this series. It's somewhat better.
I appreciate this series. A good Idea. You won't throw your money away.
