The RISM-Upper Austria database project catalogs musical manuscripts and prints, focusing on materials primarily from the eighteenth and nineteenth centuries within a region pivotal to Central European music history. Selected collections from Upper Austrian music archives are progressively integrated into the Répertoire International des Sources Musicales database—the largest archival resource in musicology—according to the scholarly standards set by the RISM central editorial office in Frankfurt.

For some archival holdings, an earlier unpublished comprehensive catalog, comprising over 4,400 manuscripts and prints from previously processed ecclesiastical archives, provides a foundational resource.

This project catalogs historically significant musical manuscripts and prints from archives primarily under ecclesiastical ownership, including those in Asten, Bad Leonfelden, Freistadt (Choral Community Archive), Gramastetten, Gaspoltshofen, Hartkirchen, Krenglbach, Linz: Glisic private library (estate of Anton Überlackner, St. Thomas am Blasenstein), Linz (Cathedral Parish, St. Matthias Parish, City Parish Linz, and City Parish Urfahr), Lohnsburg, Munderfing, Münzkirchen, Natternbach, Neuhofen im Innkreis, Reichenthal, Rohrbach, St. Florian am Inn, St. Georgen an der Gusen, Schörfling, Schwanenstadt, Taiskirchen, Wels (Hans Sachs Choir Archive), and the Cistercian Abbey Wilhering (with funding from the Wilhering Abbey). The sources cataloged span from the eighteenth through the twentieth centuries.

This initiative is supported by the Upper Austrian Provincial Government, the Diocesan Archive Linz, and the Diocesan Conservatory for Church Music in Linz at the Collegium Petrinum.
