The Library consists of manuscripts, ancient and modern books, pamphlets and periodicals – sometimes the funds are linked to the archives they were part of.
The asset consists of approximately 30,000 volumes, including 28,000 pamphlets starting from the 14th century, 320 manuscripts, and 501 periodicals.
The Library is connected to the SBN (Servizio Bibliotecario Nazionale) network and is part of the “Polo della Biblioteca Nazionale di Napoli” (National library of Naples), with a link to the “General Index of the Central Institute for the single Library Catalogue and for bibliographic information”.
