Cambridge Opera Handbooks.
This is a series of studies of individual operas, written for the serious opera-goer or record-collector as well as the student or scholar. Each volume presents a history of the work and a detailed musical analysis. Some conflict of interpretation is an inevitable part of this account, and the editors of the handbooks reflect this by citing classic statements, by commissioning new essays, and by taking up their own critical position. A final section gives a select bibliography, a discography and guides to other sources.
