The National Library of the CR has provided access to some medieval manuscripts. The oldest of them comes from the 12th century, but most of them were not written until the late Middle Ages. In terms of content, the works include the Bible and its exegeses (those whose authors have been identified comprise e.g. the manuscript III.F.18 by Nicholas of Lyra or the concordance of the Gospels by Mikuláš Biskupec of Pelhřimov in III.F.5), but also patristic and medical works (the extensive compendium by Gilbert of England in III.H.20), preaching, legal and ancient literature (Ovid’s works in III.H.24a–III.H.24c). Some manuscripts are interesting not only for their content but also for their information on former owners: the owner of the codex III.G.1 was Vojtěch Raňkův of Ježov, who had probably acquired it during his work in Paris; the manuscript III.E.34 is one of the few manuscripts that have been preserved from the library of the Reček College (Collegium sanctissimae Mariae) of the Prague university.
