Bests & Worsts Reviews from Amazon

There are two paperback editions of this book at Amazon. The 1995 edition contains the pictures that were so helpful (and entertaining) in the hardcover edition. The 1997 paperback edition has had the photographs removed. If you like beautiful astronomical photographs, order the 1995 edition. Otherwise, the book is very enjoyable, and provides a cogent discussion of where Carl Sagan thinks we should aim our space program.
