With nearly three thousand new entries, the revised edition of Operas in German: A Dictionary is the most current encyclopedic treatment of operas written specifically to a German text from the seventeenth century through 2016. Musicologist Margaret Ross Griffel details the operas’ composers, scores, librettos, first performances, and bibliographic sources. Four appendixes then list composers, librettists, authors whose works inspired or were adapted for the opera librettos, and a chronological listing of the entries in the A–Z section. The bibliography details other dictionaries and encyclopedias, performance studies, collections of plot summaries, general studies on operas, sources on locales where opera premieres took place, works on the history of operas in German, and selective volumes on individual opera composers, librettists, producers, directors, and designers. Finally, two indexes list the main characters in each opera and the names of singers, conductors, producers, composers, directors, choreographers, and arrangers. The revised edition of Operas in German provides opera historians, musicologists, performers, and opera lovers with an invaluable resource for continued study and enjoyment.
