Its resources include over 130,000 volumes of manuscripts, books and incunabula on the history of the Church from the sixteenth to the nineteenth century and palaeographic research. The collection is complemented by a valuable selection of engravings and medieval photographs. The pearl of the collection is Alcuin's Bible from the 9th century and the 12th century lectionary.
