Jesuit Historical Institute

The Jesuit Historical Institute (in Latin Institutum historicum Societatis Iesu or IHSI) is an international group of Jesuit historians committed since the end of the 19th century to bring out scientifically critical editions of the foundational texts of the Society of Jesus (the MHSI), and to promote research on the history of the Jesuits. Originally based in Madrid, the institute is now quartered in Rome. Provided by Wikipedia
