Patrick Moore must be to celestial objects what Roger Tory Peterson is to birds. In this ""New"" guide (he published an earlier pre-Eagle-has-landed edition) he savors the rich past of myth and superstition, chronicles the map-makers, lifebelievers, and creation theorists, and adds enough of the new to produce a wellrounded picture of this, our favorite satellite. Reading at a leisurely pace, one learns that Sir John Herschel, William's son, first coined the word photography, understands that the moon's mountains are higher than earth's, that it is uniformly a light concrete in color and has a surprisingly thick crust and mantle. Questions can still be raised about whether the moon was produced by fission or is part of a two-planet system; whether the volcanic rocks in relative abundance are of internal origin or produced by bombardment, and so on. The extensive appendices for dedicated moonwatchers offer advice on observing, charts detailing features quadrant by quadrant, and numerical data. Along with earlier explanations of the tides and other earth-moon-sun interactions, they provide the solid mine of information one has come to expect from this excellent cicerone.
