The first inventory of the fifteenth-century book collection, drawn up in 1448, has not survived, but Lami in his famous work Sanctae Ecclesiae Florentinae monumenta published a copy, with the addition of the titles acquired later.
The first catalog in existence today is that of 1645, preserved in the historical archive of the Opera di Santa Maria del Fiore.
Today's collection has as its original nucleus the library of the chaplain of the Florentine Metropolitan Antonio Vieri, left by will in 1814 to the Chapter. Almost all of his books, the titles of which are listed in the tome of the Various Scriptures L (preserved in our historical archive), have been found.
Currently the library consists of about 10.000 volumes, including 132 sixteenth-century and 85 manuscripts. The oldest edition is a historical collection published in Florence in 1517 (BC mis250), while the manuscripts have been compiled starting from the sixteenth century. The ancient section was increased by the donation of the library of the Ecclesiastical Boarding School and of a part of the library of the Martelli family. The modern part is mainly composed of works of Tuscan historical-artistic-folkloric and religious subjects.
