The manuscripts of the National Library of the Czech Republic that have recently been made accessible can be divided into three smaller groups. The largest group comes from the old Klementinum collection and includes medieval manuscripts of Czech origin. Their content is quite varied – they comprise theological, medical, astronomical as well as legal works. Manuscript VI.F.17 contains a collection of sermons, compiled by Mikuláš Mníšek, using also some texts of John Hus. Another three digitised codices come from the collections of the former Prague Lobkowicz Library – these are two manuscripts from the 12th–13th centuries acquired from the library of the Premonstratensian monastery in Weissenau and the so-called Heermann’s Rožmberk Chronicle. The smallest is the two-volume anti-Lutheran work Dictionarium Lutheri by Joseph Ernst Barisien.
