Church History (Patristic Era, Ecumenical Councils, the Papacy, and Saints): Saints

Finding information on Saints

For basic biographical information on Saints, consult one of these print resources or websites.  To locate specific proclamations of canonization or beatification, try the Vatican website, or consult our theological databases and indexes, either online or, for older proclamations, try our historic print indexes like the Catholic Periodical and Literature Index (CPLI) in the Ireland Library Reference Room.  Ask a librarian for assistance.  In some cases, it will be very difficult to find supporting documents, as they are unpublished, but the historic CPLI should help you locate published documents in sources such as L'Osservatore Romano, Acta Apostolicae Sedis, or English-language publications such as Origins.
