The Mozzi Borgetti Municipal Library, built in 1773 in the premises of the College of the suppressed Society of Jesus, is the historic municipal library of Macerata. Founded on the numerous donations received in almost two hundred and fifty years of activity, the library takes its name from the brothers Bartolomeo and Giuseppe Mozzi, belonging to a historic family from Macerata, and from the Dominican Tommaso Borgetti, who in the first years after the opening of the Library were protagonists of the more important bequests and the allocation of fundamental economic subsidies to guarantee public access to the library fund. The constant increase in donations received over the years make it one of the most important libraries in the Marches and in the whole of central Italy: it has over 350,000 volumes, including over 10,000 manuscripts, 300 incunabula and over 4,000 editions of the sixteenth century. The photo library, set up as a specific section of the library in the 1970s, contains over 37,000 images, as well as 56,000 negatives on glass plate that mainly document local history (events, characters, customs, urban planning, monuments, works of art).
