The Associated Archives

One of the most significant collections of Catholic Church history in the U.S.

The Associated Archives at St. Mary’s Seminary & University opened in the spring of 2002. Located on the campus of the nation’s first Roman Catholic seminary, this program brings together the archives of the Archdiocese of Baltimore (est. 1789), St. Mary’s Seminary & University (est. 1791), and the Associated Sulpicians of the United States (U.S. Province est. 1903), making it one of the most significant repositories for records relating to the early history of the Catholic Church in the United States.

A state-of the-art-facility was built to house the three archives. We offer researchers a spacious reading room in a climate-controlled (i.e., cool) environment that has a reference library and a digital microfilm reader/printer. Researchers are able to access the collections through the existing card catalog system and typed finding aids. Click here to read a description of our open collections.
