Knights of Columbus Vatican Film Library

It is located in the Pius XII Memorial Library on the campus of Saint Louis University.

As of 2007, the Library has microfilmed versions of over 37,000 manuscripts, with material in Greek, Latin, Arabic, Hebrew and Ethiopic, as well as several more common Western European languages.

There are reproductions of many works from the Biblioteca Palatina and Biblioteca Cicognara at the Vatican, as well as Papal letter registers from the Archivio Segreto Vaticano (Vatican Secret Archives) from the 9th to 16th centuries, in the series Registra Vaticana and Registra Supplicationium.

The collection also includes many hardcopy works on the subjects of palaeography, codicology, illumination, and other topics related to manuscript studies.

The Library hosts an annual conference on Manuscript Studies, which is held in St. Louis in mid-October.
