The George M. Troutman Papers, dated circa 1928-1935, contain materials created or collected by George M. Troutman that mostly relate to the first Byrd Antarctic Expedition and document Troutman's connection with some of the expedition's members. In particular, the papers document his relationship with Sidney Greason. Materials include correspondence, photographs, and newspaper clippings. Also included are covers, which are self-addressed, stamped envelopes that have been sent through the mail, that Troutman collected during the second Byrd Antarctic Expedition.

The Robert S. Oesch Papers, dated 1955-1984, consists of covers, newspaper articles and clippings, stickers, and other materials related to Oesch's interest in Antarctica’s postal history and polar philately. The covers are stamped from a polar philately collector in Argentina and feature postage stamps that commemorate Argentina's Antarctica expeditions, the creation of bases in Argentine Antarctica, and the Falkland Islands. Newspaper articles, clippings, and the Antartida magazine feature stories about people's experiences living in Antarctica, updates on scientific and professional developments related to Arctic expeditions, and polar philately. These papers also include lists of covers sought out by polar philatelists and a timeline of Antarctica's postal history. Some materials in this collection are in Spanish.
