Controversial publisher Lyle Stuart (1922-2006) was a self-described "First Amendment fanatic." He founded two publishing companies, Lyle Stuart, Inc. and Barricade Books, and published newsmaking and bestselling books, including The Sensuous Woman and The Anarchist Cookbook. The collection consists of 35 linear feet documenting Lyle Stuart's personal and professional activities, including his prolific correspondence and journalism, and his many lively (and often litigated) personal feuds.

Correspondence, notes, articles, reports, and speeches of Gildersleeve, including materials relating to the United Nations Conference in San Francisco, 1945, the Dumbarton Oaks Conference, the International Federation of University Women, the American Association of University Women, the American Council on Education, and the Near East College Association. The most note-worthy item in the collection is a letter from President Franklin D. Roosevelt, appointing Dean Gildersleeve to serve as a member of the U.S. Delegation to the Charter Conference of the United Nations. The collection also contains some material relating to Barnard College affairs.
