The digitised documents from the Slavonic Library come from the period between the 16th and 18th centuries. They include both manuscripts and printed books; apart from Old Church Slavonic, they are also written in Old Croatian. The most important works for cultural history are the Ostrog Bible, the first complete printed edition of all Bible books in Old Church Slavonic from 1581, and the first printed edition of an evangeliary in Ukraine (Lvov, 1636).
