The collection consists of eleven boxes of materials from Dr. Hewitt's research and teaching, and primarily professional correspondence. Those materials include manuscript transcriptions from centuries-old music manuscripts scattered in libraries across Europe, research for articles and conference papers, teaching materials and student projects, speeches, and unpublished writings, along with a box of concordance cards from the preparation of her edition of Ottaviano Petrucci's Harmonices musices odhecaton A.
