The Esar Levine Collection of Frank Harris consists of the writings, correspondence, and printed matter of, and relating to, Frank Harris (1855-1931) as collected by Esar Levine (1899-?), Harris's disciple, agent and friend. Harris, an Irish-born, naturalized American citizen, was a prolific writer and journalist/editor who is perhaps best known for his scandalous autobiography, My Life and Loves, which was censored in America and parts of Europe.

The collection contains both original and printed material relating to Albert Schweitzer, the French missionary physician who founded the Lambaréné Hospital in French Equatorial Africa in 1913 and who won the Nobel Peace Prize in 1953 for his philosophy of "reverence for life."

Consists (primarily) of manuscripts of works by Handel and his contemporaries but also of correspondence and subject files gathered by James S. Hall, the English surgeon who collected most of the manuscripts.

The Stella Bloch Papers Relating to Ananda K. Coomaraswamy consists of manuscripts, correspondence, drawings, photographs, printed material, and postcards of the American dance critic, art historian, and artist Stella Bloch (1898-1999). This collection documents the relationship between Bloch and the Anglo-Indian art historian, philosopher, and author Ananda K. Coomaraswamy (1877-1947) who embodied the roles of mentor, husband, and friend. The papers primarily contain correspondence by Coomaraswamy to Bloch, as well as a small amount of other letters. Writing was a vital form of communication for Coomaraswamy and Bloch, especially during their marriage, since they always resided in different cities; he lived in Boston while she lived in New York. There are also drawings by Coomaraswamy and by Bloch, as well as photographs-some taken by Coomaraswamy-that include portraits and assorted images from their travels to India and Southeast Asia. The articles in both manuscript and printed form provide a sampling of Coomaraswamy and Bloch's writings on art, religion, and philosophy. Furthermore, there is a small selection of printed material about Coomaraswamy and Bloch, and a series of memento postcards.
