Encore is the Finnish National Opera and Ballet performance database, containing information on opera and ballet performances of the FNOB and its predecessors, Kotimainen Ooppera (the Domestic Opera) and Suomalainen Ooppera (the Finnish Opera), since 1911. There is a comprehensive search function to help find information about works performed and production teams.

The information is organised onto three levels: works, productions and performances. Individual persons and groups of performers may also be used as search terms.
