In 2024, the National Museum Library provided access to four medieval manuscripts of Czech origin. Illuminated codices are represented by two missals of the Prague diocese, XVI B 12 from around 1330 and XIV A 1 from the beginning of the 15th century. The manuscript XVII E 2 from the turn of the 15th century contains the travelogue of Odoric of Pordenone and the treatise of Guillaume (William) Durand Rationale divinorum officiorum, whereas XVIII A 40 from 1398 includes Postilla studencium sancte universitatis Pragensis, the Latin version of the Postil of the Students of the Prague University by Conrad Waldhauser.
