This collection consists primarily of bibliographies, poetry, journals, and programs documenting Donald C. Gallup's work in 20th century literature. Many of the publications are personally addressed to Gallup by the author. The collection also houses postcards (depicting such subjects as Belfast, the British Museum, Peterborough Cathedral, and various celebrities) that Gallup accumulated during his travels in Europe, a few personal photographs of Gallup and his friends (including author Gertrude Stein and the circle of American émigrés revolving around her), and a videotape entitled Tao House Award Dinner, June 23, 1994, Highlights of O'Neil on World Stages Conference. Most of the postcards are blank, but a few include correspondence to friends and family, including an aunt Ella.
