Watkins' correspondence could not be completely separated from the general business flow, for she was integrally involved there as well. Consequently, those letters concerning her role as executrix of J. B. Watkins' estate, the administration of her household staff, and her numerous bequests to individuals remain in the Lawrence office series of the collection. At her death in 1939, her business manager, Dick Williams, was appointed executor of her estate. Materials regarding her will and the administration of her large estate can be found in the "Elizabeth M. Watkins Estate" subject folders in the Lawrence series.

The Kansas University Archives houses some of the original blue-prints for the Watkins Memorial Hospital, now Twente Hall on the KU campus. In addition, Architectural Services maintains current plans and blueprints of most campus buildings, including those built by Elizabeth M. Watkins.
