House of Farnese
The first librarian was the Theatine priest Paolo Maria Paciaudi, who was assigned as "Antiquario e Bibliotecario". The goal was to form a public library as part of a project by Duke Filippo's prime minister, Guillaume Du Tillot. The library lacked many of the works that had been collected by the House of Farnese while ruling in Parma, when the future Charles III of Spain, brother of Filippo and who was Duke from 1731 to 1735, moved the local library and archives to Naples in 1736.
