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 Walter Giles Correspondence to Ruth Giles While Serving on the U.S. Antarctic Service Expedition contains two letters sent by Giles from Antarctica to his sister, Ruth Giles, dated 1939 and 1940. Giles writes about missing his hometown in Georgia, the weather, activities on base, and plans to visit Georgia once he returns to the United States. One of the envelopes sent to Ruth Giles has a Pitcairn Island cover, cancelled at Pitcairn Island 14 December 1939.
