In 1872 Józef Przyborowski (1823−1896) was appointed the director of the Zamoyski Family Fee Tail Library (Biblioteka Ordynacji Zamojskiej, BOZ) in Warsaw. This philologist, historian, numismatist, and archaeologist, former professor of Polish language in the Main School (Szkoła Główna) in Warsaw and the director of its Library, was an expert in the life and works of Jan Kochanowski and the 16th century prints. When working in BOZ (until his death), Przyborowski not only arranged and developed the collections of books and manuscripts, but also transformed it into a workshop for his editorial works and his studies as a historian of literature and bibliography. Przyborowski’s academical and educational publications in the periodicals, encyclopaedias and editions of Old Polish literature were popularising the knowledge of Polish history, literature, culture and library collections. The article presents Przyborowski’s publications, based on the collections of Zamoyski Family Fee Tail Library, and their importance in the history of old books and literature.
