Opening Night! Opera & Oratorio Premieres
According to the website, "this application is a cross-index of data for over 38,000 opera and oratorio premieres. Originally compiled by Richard Parrillo, entries include works that received a public performance between the years 1589-1995." This Stanford University online resource has a very user-friendly search function, making it possible to track down rare works and compare operas/oratorios based on adaptations of the same libretti. It is possible to narrow your search by opera type (e.g.: operetta, intermezzo, Singspiel), librettist/literary source (e.g.: Metastasio, Shakespeare), composer, premiere date, location (country, city, theater), etc. For oratorios it is possible to set the search parameters to subject/theme (e.g.: The Passion, Abraham and Isaac) and feast month and date, once again making it possible to compare works based on the same or similar themes/texts.
