As far as I know, this is his only book. I really like the material in it, it's good visual stuff, a bit like a warm-up By Forces Unseen, although you do need a table for a lot of it. I understand the new edition that Dan and Dave are selling has some extra annotation that the original didn't have. I've got a first edition, so I'd be interested if anyone knows whether the extra stuff is worth buying a new copy.
