Four manuscripts of the Royal Canonry of Premonstratensians at Strahov have been digitised. The earliest of them is a collection of the works of St John Cassian, written in the monastery of Hradisko near Olomouc in the 1130s–40s (DA III 25). The collection DA IV 42 comes from the library of the monastery in Weissenau. The Bible DA IV 22 was made in the Czech lands. Salzburg seems to be the place of origin of the catalogue of the local bishops and archbishops (DA II 28) created after 1615, which is complemented by their coats of arms.
