In a fascinating survey of research and findings, [Melvin Berger] makes a complicated subject clear [in Enzymes in Action], explaining the nature of enzymes, the ways in which they act, and the isolation … of a pure enzyme that led, in addition to other experimental work, to the production … of a synthetic enzyme…. Lively, informal, and informative, this is not only good science for the layman, but also a good picture of scientific method. (pp. 117-18)

[The Violin Book is variously] entertaining and inspiring background material for young performers…. Berger also gives some hints about repertoire and advice on career possibilities, but since he still believes in the efficacy of the self-organized New York debut ("You hope that the newspaper critics who usually attend these concerts will write rave reviews") it's hard to place much faith in the practicality of his recommendations.

[Enzymes in Action] is a short up-to-date review of enzymology and its practical application in industry. Berger covers adequately such topics as the role of enzymes in digestion, food production, and preparation of beverages; enzymes as drugs; enzymes and diseases; and enzymes at work. He describes historic and salient discoveries including the latest achievements in enzymology. The book is written in a highly simplified style. Because the vocabulary is simple, the book can be read easily by a layman. The text can be used with great profit as a collateral reading by a freshman student of biochemistry, biology, agronomy, agriculture, or medicine. Although the author uses no chemical formulas, such classical effects on enzyme activity as those of pH, temperature, and concentrations of enzyme and substrate should have been mentioned. (p. 46)

Though none of it is essential to their music making, young flutists [reading The Flute Book] will enjoy meeting their famous predecessors from Frederick the Great to Jean-Pierre Rampal, tracing the innovations that led to the standard flute designed by Theobald Boehm in 1847, seeing how modern instruments are made, and learning a little about the physics of the flute's sound and a little more about the highlights of the concert repertoire. And, given the instrument's resurgent 20th century popularity, those with a sense of humor will appreciate the 19th century image of the flutist: "He always has a pointed nose, marries a nearsighted woman and dies run over by a bus." Grace notes all, but pleasantly orchestrated. (p. 561)
