A huge paper heritage, made of the volumes of the Library and the manuscripts of the Historical Archive, is preserved at the Observatory.
The Historical Library owns incunabula, cinquecentine and seicentine, a considerable stock of the 18th, 19th and 20th centuries; there are more than 30,000 titles altogether.
