The thesis analyses two private libraries on the island of Korčula, based on their 19th-century inventories. The library of the Arneri family, with 469 titles in 578 volumes, is an example of a city-based complex family library. The library of Franko Franulović, a Roman Catholic priest from Blato, had 79 listed titles in 159 volumes. It comes from the rural, predominantly agricultural western part of the island. Bibliographic research and content indexing (to classes and subjects), as well as other archival records and relevant bibliography have revealed that the Arneri library represents a crucial link in a centuries-old tradition of Korčula`s private libraries. The oldest editions were printed in the 16th century. Its beginnings can probably be dated to the same century. The inflow of books continued throughout the next few centuries. At the turn of the 19th century, it probably represented the largest private library on the island. In the regional context, it is of medium size, but typical in terms of its contents. Reflecting the needs and tastes of its family members, the collection shows an array of themes, such as literature, law, religion, history. Its distinctive mark is a rich collection of law books. The language of the library is Italian, with prevailing works and editions of the 18th century. The collection is focused on Italy as well as Dubrovnik and Korčula. The library of priest Franulović was developed by the sole efforts of its owner in the second half of the 18th and beginning of the 19th centuries. The prevailing religious themes and number of works reflect the needs of a well-educated pastor.
