Another part of the manuscripts from the collections of the National Library that have been made accessible contains mainly modern handwritten copies of earlier historical sources coming from the Thun-Hohenstein library in Děčín (shelf mark XIX); handwritten copies of works by Bohuslav Balbín can be found in the two-volume manuscript XXIII.C.40. The medieval codices that have recently been digitised are of Czech origin and were written in the second half of the 14th century and at the beginning of the 15th century; in terms of content, they are an assortment of sermonic, mystical, natural-science, theological and philosophical works.
