Now any person can look at these documents by going online. The site shows 12 volumes, comprised of internal documents from the Holy See. The collection of documents about the conflict are written in French and Italian.
The volumes include original written agreements made in World War II, the humanitarian activities of the Church, the letters that Pius XII sent to the German bishops before and during the war, and other related documents to Poland and the Baltic countries.
In 1965, Pope Paul VI oversaw four Jesuit historians that collected a selection of the documents on the war in the preserved Vatican archives.
The historians published them in successive volumes from 1965 to 1981. Now they are also available on the internet.
