Index of Opera Incipits
The index of opera incipits

Index of Operas under Composers
The index of operas under composers lists all operas covered in The Grove Book of Operas under the composers who wrote them, alphabetized by composer.
Index of Opera Roles
The index of opera roles
allows users to browse major opera roles from A to Z with ease, and
includes hyperlinks to the operas, composers, and singers who created
