It's layout is pretty ambitious, but it is poorly lectored. Content is okay, though I would have liked to read more about tracking in it.
But if you need a book about the Golden Era with not only the stories and pictures in it you've already seen and read a hundred times, this is a book you should get. And when it comes to Apollo only, try to get the three-volume Time-Life set of Andy Chaikin's 'A Man on the Moon'. B&N currently sells it for $7 per volume. Original price tag was around $100 for the whole set. A real bargain.
