De Filippi Donation
Most of Bruno's music collection (records, music sheets, books and methods) has been donated by his family to the historical Biblioteca Sormani in Milan.
His LPs have been classified in detail; you can see and book them here.
His CDs have been classified too in the same way; you can see and book them here.
Note: you can listen to the listed records only in the library (online listening is not allowed due to copyright).
