In December 2001 a collection of over 5,100 music manuscript scores was rediscovered in Kiev, having been missing for over half a century since its disappearance during World War II. This vast collection belongs to one of Europe’s oldest continuing choral societies, the SingAkademie zu Berlin, and soon after its discovery the collection was repatriated and now resides in the Staatsbibliothek zu Berlin–Preußischer Kulturbesitz as a permanent deposit of the Sing-Akademie (D-Bsa).
