The library is located on the first floor of an ancient building called "Il Pellegrino" (the Pilgrim), named after a hostel for travellers founded by the SS. Annunziata Church Company. Over time the building served also as Oratory of S. Filippo Neri, traces are still visible in the premises.
Books are kept on open shelves. Most of the items on philosophy are held in the main branch in piazza Brunelleschi and they are located in the namesake thematic reading room on the ground floor and in the bookstacks.
The collection highlight is Fondo della Biblioteca Filosofica (in italian), a sizeable collection of 9,800 volumes, rich in rare editions from 16th and 17th centuries, whose topics range from philosophy to religion. This collection followed the establishment of the Philosophic Society at the beginning of the 1900s upon the initiative of a group of illustrious scholars. After the Society's suppression in 1942, the material was donated to the Humanities Library where it is considered one of its most precious historic collections.
