This book is a real joy. Bud is so big-hearted and full of enthusiasm and excitement about his subjects that I cannot help but take a walk alongside him. I've been working my way through a number of old 50s/60s anthologies, and this volume has been an invaluable companion in extending my horizons in the science fiction universe.
I thought the chapter on Clifford D Simak by far the best on this wonderful author that I have read, really capturing the essence of his writing. There are also excellent chapters on Murray Leinster, Cordwainer Smith, Zenna Henderson, H.Beam Piper, Fredric Brown, Nelson Bond, Leigh Brackett, Edgar Pangborn, Cyril M. Kornbluth, Henry Kuttner, Eric Frank Russell, Judith Merril, Phil Klass, Hal Clement, Stanley G. Weinbaum, R.A.Lafferty, Tom Reamy, together with summaries of various of Bud's more unusual personal favourite books. I also really liked the three chapters of wide-ranging discussions with Jerry Pournelle and the chapter on the history of the SFWA Bulletin. I really enjoy his style of writing and the occasional arcane musical reference (such as to the Fugs and early Mothers of Invention).
All in all, if you have any interest at all in the science fiction of the 1950s and 1960s, you will love this book.
