Check <http://www.Jemi.it> it is linked to The Eparchy of Lungro. It is possible to join the forum, has a great deal of information. I requires a user profile, very professional.
Also check the Grottaferrata Monastery, Rome. Library and archives : superb collection. Must present credentials to do research there.
Also, recently the Eparchy inaugurated a Seminary in Cosenza for the training of priests. I believe they will have good sources available.I plan to visit. I will pass on other information as I come by.
