The library is one of the oldest public libraries and contains some 16,000 volumes dealing with topics of a religious, philosophical, theological, juridical, historical, literary and scientific nature. It takes its name from Mons. Vittorio Giovardi (1699-1786) who was a “Decanus Utriusque Signaturae” in the Supreme Court of the Church of Rome. The dean was born in Verona and donated his collection to the city with a testament dated January 20, 1773.
Of great importance are the manuscripts represented by 10 parchments with miniatures ranging from the 12th to the 16th century, 280 paper manuscripts, 42 fifteenth-century incunabula, hundreds of parchments, five hundred and a thousand engravings, drawings by Carlo Maratta and other unknown painters of the XVI-XVII-XVIII centuries.
The library preserves the furnishings and the original layout of the eighteenth century which included two rooms: one for reading and one for storage in closed shelves and in a high room with a balcony to access the upper levels of the shelves.
In the palace there is also a collection of votive offerings, coins and Roman jewelry.
