The principal service rendered to the public is to ensure consultation of archival material. This activity takes place in the reading room, which is open from Monday to Thursday from 8.30 to 17.25 and Saturday morning from 8.30 to 13.30.
In addition to the reading room there are other services, all designed to allow users to gain the maximum benefit from the documentary patrimon. They consist of:
- a laboratory of photo-reproductions that makes reproductions of documents, upon request of the users, on the basis of fees defined by ministerial tariff;
- an internal library of the Institute that is at the disposal of the scholars for use only within the Institute.

Very appreciated are also the educational activities, aimed at students of all levels of study.
