Youthful space scientists will be fascinated by Franklyn Branley's careful and often dramatic examination of the earth's newest "rock collection" brought back by the lunar astronauts of Apollo 11, 12 and 14. Early chapters [in Pieces of Another World: The Story of Moon Rocks] discuss the methods and tools used to collect moon rocks, the techniques used by scientists at the Lunar Receiving Laboratory in Houston to analyze them, and what they have discovered about the various rocks, dust, and crystals. A scant chapter is devoted to the few questions tentatively answered by moon rock findings, while subsequent chapters (over one-third of the book) explore the many questions these findings have raised about the moon's origins and geological structure. Dr. Branley's text is often marred by the lack of italics to emphasize technical terms and their definitions. No glossary alleviates this problem, and important concepts are often lost in a sea of text…. Dr. Branley's work … examines with clarity the careful scientific procedures and diverse theories resulting from this new and exciting lunar data. (pp. 8-9)
