The present volume, the third and final part of the catalogues of the music collections at the Graz Institute of Musicology, comprises manuscripts and prints from the Musikverein für Steiermark and the Dommusik-Archiv Graz. The oldest manuscript of the Musikverein is dated 1791; most of the collection (until the middle of the 19th century) is from the time of Kapellmeister F. E. X. Hysel (the Elder) and his successor J. Haag. The beginnings of the Dommusik Collection (ca. 1810) range from the time of the Regens Chori D. Wasser to the middle of the 19th century. Both collections contain complete music estates. The most extensive are those of J. B. Stumpöcker, F. X. P. Posch, L. C. Seydler and J. Deibl. Newly discovered compositions and biographical data complete the catalogue.
