In the process of compiling and cataloguing the World Student Christian Federation (WSCF) archive at Yale in the 1940s, Rouse split her own papers. Portions she added to John Mott’s collection, in order to fill gaps and enhance the official WSCF archive. Those records mostly include official reports, correspondence with other WSCF leaders, and some of Rouse’s notes on the history of the WSCF, and can be found in RG 46. The remainder of her papers she either sent to the main WSCF offices or retained in her home; this portion is generally of a more personal nature, and comprises this collection. About half of the collection was processed as part of the WSCF archive in Geneva (as boxes 213.50.1-213.50.7); because it pertains mostly to Rouse’s work outside the WSCF, it has been separated into its own collection and re-processed along with five boxes of previously unprocessed material.
