A large number of annual reports are included in the catalogued collection. These can be searched from the Fennica database.
In the Ephemera Collection, annual reports up to 1972 are in the same collection with other publications of the same publisher. Since 1973, annual reports have been collected in their own group.
Annual reports are also included in various publications, such as yearbooks and periodicals, so they may not all be found in the catalogues or directly in the collections.
