This catalogue is the first coherent descriptive list of the manuscripts of the libraries of the Augustinian canons in Roudnice as well as in Sadská, which was incorporated in the Roudnice library still in the Middle Ages. Although there is no surviving medieval catalogue of the Roudnice library, it was possible to identify 166 manuscripts once held there on the basis of ownership marks and the system of shelfmarks.
Most of these manuscripts are kept today in the Library of the National Museum in Prague but there are several in the National Library of the Czech Republic in Prague, the Archives of the Prague Castle - Library of the Metropolitan Chapter, the Moravian Library in Brno and the Archives of the Cracow Cathedral Chapter. Three more lists are included: a list of the manuscripts that used to be owned by individual canons from Roudnice, but their presence in the Roudnice library cannot be documented, a list of manuscripts whose provenience from Roudnice is supposed but not clearly documented, and finally a list of the manuscripts that have been linked to Roudnice in the past by mistake.
