Leonard and Harriet Arrington established The Leonard J. Arrington Historical Archives at Utah State University in 1995.
The purpose of the LJAHA is threefold: to provide a home for Leonard J. Arrington's personal and professional papers, to
house historical materials and papers from other members of the Arrington family, and to serve as a respository for the
papers of other scholars in the field of Mormon History. The LJAHA currently holds two major collections,
the Leonard J. Arrington Papers (LJAHA MSS 10) and the Conway Sonne Papers (LJAHA MSS 8).
