I got a copy of this book at a Goodwill a long while ago; it has a different cover (sort of a Stonehenge-esque monument on the Moon's surface). It's a pretty batshit fun read. I looked it up on Amazon a while back too and saw copies going for more than $100!
Gah! I *used* to have this! I cut out some of the chapter headings from the contents page to use as titles on the sides of compilation tapes, cos they sounded so good: "The Moon's Peculiar Internal Strength" is a memorable one.
