But for somebody who does care about the history of SF, this would seem to be an essential book. It's fun because of the stories, of course, but each writer provides a short introduction to explain why a particular story was picked for the collection. (My favorite line in these is the final one in Henry Kuttner's intro: "Anyway, my wife wrote it.")
You have to wonder, considering the date of the collection (1949) if the writers would have chosen different stories later on in their careers. Too bad they're not around to ask. Cheap copies abound around the Internet, so why not pick one up an give it a try. See if you agree with the authors' choices.
