The archive of the Sibelius Museum stems from professor Otto Andersson’s (1879-1969) private archival collections. Nowadays the archive owns collections concerning individuals, orchestras, choirs, different musical organisations etc. The primary types of materials are different kinds of manuscripts, printed sheet music, photographs, sound recordings and collected press clippings. Some parts of the archival collection (e.g. the bulk of the photo collection) are registered in databases. An important part of the collections is also registered in the archive’s card catalog.

The archive also owns several special collections, e.g. the collected material on Jean Sibelius, the Otto Andersson archival collection and the archive of the Musical Society of Turku.
