I read this book a few years ago so don't recall much about it. It is an old study of science fiction. Contrary to the book description for this and the other 'Ace' edition, it is not in German, but is published in American English! ( )

Quite informative, though obviously dated, guide to Science Fiction. Just remember it came out in 1971 and who was still alive then. ( )

Nice overview of the genre from a Swedish science fiction writer. ( )
