The DeAndreis-Rosati Memorial Archives serves as the provincial archives for the Western Province (U.S.A.) of the Congregation of the Mission.  The provincial headquarters are located outside of St. Louis, Missouri.  Since 2001 the archives have been located in the Archives and Special Collections Department of the John T. Richarson Library of DePaul University in Chicago, Illinois.  The university was founded by the Vincentians in 1898.  The archive documents the activities of the Vincentians especially in the Western half of the United States since the arrival of the first Italian missionaries in Baltimore (1816).
