The study deals with four codices complementing the recently published catalogue of manuscripts coming from the houses of Augustinian canons in Roudnice nad Labem and Sadská. Two of them are deposited in the collections of the National Library in Prague and the other two in the Library of the Metropolitan Chapter of St Vitus, administered by the Archives of Prague Castle. In terms of content, these manuscripts enrich the Roudnice collection especially with hagiographical and historiographical works. Both manuscripts of the National Library provide information on the fate of the monastic library in Roudnice after the dissolution of the monastery, when its library became part of the library of the Zajíc family of Hasenburg. The paper contains a codicological description of the four manuscripts.
