The collections of the Archivum Romanum
ARSI is the archives of the central government of the Society of Jesus worldwide. It does not hold all Jesuit collections that scholars might seek. For example, the Fondo Gesuitico dei Manoscritti (Jesuit manuscript collection) is held by the Biblioteca Nazionale Centrale Vittorio Emanuele II, and by the Archivio di Stato, Rome. The Vatican Archives also has considerable holdings relating to the activities of Jesuits.
For a description of the archives holdings see F. Danieluk’s article.
Some ARSI materials for North and South America may be consulted on microfilm in St Louis University, MO, USA:
