Continuing the tradition begun with The New Penguin Stereo Record and Cassette Guide ( LJ 2/1/83), this familiar group of highly respected critics has compiled a very useful survey of classical music on compact discs and cassettes. The authors discuss the artistic merits and sound quality of each recording in evaluations that are extremely perceptive and educational. Audiophiles will be happy to know that the authors indicate whether or not the recording has been recorded digitally or remastered from an analog original. Those on a budget will appreciate the inclusion of bargain-priced editions. And music lovers in general attempting to navigate the maze of CDs currently available will find this work indispensable.-- William J. Waters, Pensacola Junior Coll., Fla.
