The Archivum Romanum Societatis Iesu (ARSI) is the central archive of the Society of Jesus, and it mainly preserves Father General’s correspondence with the Provincials and Superiors, and the administrative records that the General Curia received periodically, such as historiae domus and litterae annuae. ARSI also preserves catalogs of the Society. Catalogs of the New Society are also available online. Historical archives of Provinces preserve documents produced by individual Provinces, colleges, institutes and member Jesuits.
