Having completed a deep research of historical documents after the conclusion of the Diocesan Phase for the Beatification of the Servant of God, the Reverend Prince Demetrius Agustine Gallitzin, a lot of material ? mostly unedited or very difficult to obtain ? was collected and ready for further investigation in order to promote a renovated study on the works, time and activities of the Founder of the town of Loretto and the entire Catholicity in Western Pennsylvania. Now, we have the privilege to present four Academic works prepared many years ago and currently unavailable for researchers, with the intention to put them at disposition for further studies.
