"Opera is the only guide to the research writings on all aspects of opera. This second edition presents 2,833 titles - over 2,000 more than did the first edition - of books, parts of books, articles, and dissertations in European languages, with full bibliographic descriptions and (except for dissertations) critical annotations. Users will find the core literature on the operas of 320 individual composers, and about operatic life in forty-three countries."--BOOK JACKET.
