The collection consists primarily of typescript copies of literary works by the American expatriate author Frank Harris, arranged by form and genre. Many have been heavily revised and corrected. Most of his published books are represented in some part, though shorter pieces, such as articles and contemporary portraits, predominate. A major part deals with his criticism and interpretation of various works by Oscar Wilde, his biography of Wilde, and his own biography, My Life and Loves. Correspondence of Harris from his last decade (primarily letters from booksellers, translators, and publishers), as well as some financial and printed material, is also included

Further accessions include correspondence with Arnold and Blance Rittenberg, and Gordon Young.
