Starting from 27 September 2019, the 135th anniversary of the opening of the Opera House, the DigiTheca, the digital archives of the OPERA, has been available to the general public. The popular database, which has been under development for a decade and a half, has been welcoming researchers and enthusiasts of the OPERA’s past with a renewed design and a more user-friendly interface since autumn 2024. It currently includes 60,236 performances, 7429 artists, 10,500 roles, and more than 6000 archive and new photos from the period between 27 September 1884 and 1 March 2025. Over the past years, the DigiTheca has become the world’s most comprehensive, free, and fully open institutional opera database, with 13 000 users and 25 000 views per month – and there is still room for improvement in the coverage of further concerts, galas, and solo recitals held at the Opera House.
