The SIDIC Rome Documentation Center makes available to the public a large collection of documents concerning Jewish-Christian relations. It comprises about 6.200 entries that may be retrieved by electronic catalogue, now available on-line.

The Collection of these documents has been going on since the 1960's, that is, since the time of the Second Vatican Council, especially since the promulgation of the declaration Nostra Aetate, in 1965.

It includes articles drawn from magazines and newspapers, texts of lectures, material collected in dossiers, and official declarations by both Jewish and Christian bodies throughout the world. The documentation also includes about 150 periodicals (magazines and newsletters), many of which have been bound, which also go back to the 1960's.

After having been active for over 30 years at the SIDIC headquarters in Via del Plebiscito, the documentation service moved to the Pontifical Gregorian University in July 2002. The Documentation Center continues to be owned by the Congregation of the Sisters of our Lady of Sion.
