The papers consist of correspondence, short writings, notes, memorabilia and printed matter. The correspondence is largely made up of letters commenting on Freeburg's writings on Elizabethan drama and Hesselius. Other writings relate to ciphers and codes. Also in the papers is a scrapbook containing memorabilia of Freeburg's years at Yale together with a play entitled Sunset, produced at Yale in 1908 and acted in by Sinclair Lewis. A second scrapbook (1905-1913) reflects Freeburg's early career teaching at the U.S. Naval Academy, the College of the City of New York and contains copies of his writings and speeches.
