The original copyright date for [The Moon: Earth's Natural Satellite] predates the adventures and discoveries of the manned lunar landings of Apollo. This edition has been updated with only a cursory and superficial acknowledgment of Apollo. This is not bad, however, since it leaves room for much of the fundamental coverage of lunar science and the earth moon system which would otherwise be displaced by material covered elsewhere in many new books about Apollo. However, although the organization is logical …, the text has many serious flaws. On page 24, the author identifies the intersection of the ecliptic with the horizon as being in the constellation Aries. It hasn't been there since ancient times. On page 25, he equates the ecliptic with the moon's orbit. They are 5 degrees different…. He confuses the convention for the east and west sides of the moon's face, both as seen directly and by inverting telescope. This, of course, disagrees with the correct convention shown later in a NASA lunar chart reproduction. These and other errors are too serious to ignore. Without them the book would be very good. As it is, I rank it only fair.
