The Centro Pro Unione in Rome is the ecumenical center for the Eternal City, and the main library for the ecumenical section of the theology faculty at the Angelicum. Housed in the Collegio Innocenziano overlooking Piazza Navona, it was once one of several ecumenically oriented institutions in the building, including the Lay Centre, Casa Foyer Unitas, and Taize. It is the site of the Thursday debriefing during the Council for ecumenical observers, who were staying upstairs as Foyer Unitas at the time.
Its director, Prof. James Puglisi, SA, is also director of the ecumenical section at the Angelicum, and has started a blog here: Ecumenism Around the World: http://atonement-ecumenism.blogspot.it/
From the American branch of the Society of the Atonement, based at Graymoor, NY, comes the monthly publication Ecumenical Trends and the homonymous blog, http://ecumenicaltrends.blogspot.it/
