A subsidiary database has been created as part of the APVV and Mobility projects with the Augustinian Library in Klosterneuburg http://austriamanus.org, in which notated fragments used in their secondary function as “recycled” materials (maculature) on other manuscripts, prints, incunables or archival documents were processed. The database is linked to the global portal (network) of medieval notated sources http://cantusindex.org. Doctoral and postdoctoral researchers of the Institute have taken an active part in data import (H. Studeničová, E. Lazorík, V. Garajová).
