The Herwil M. Bryant Papers, dated circa 1930s-circa 2000s, contain materials that Herwil M. Bryant created or collected while serving on the United States Antarctic Service Expedition from 1939-1941. This includes his journals, both the handwritten originals and photocopies and typed transcriptions of the originals. Also included are photographs, negatives, and photographic slides that he created during the expedition as well as correspondence, notes, press clippings, objects, and ephemera. In addition, the papers contain notes and other materials related to lectures Bryant gave about Antarctica and his experiences during the U.S. Antarctic Service Expedition, including lectures he gave aboard Antarctic cruises. Photographs he took during Antarctic cruises are also included. There are two USB flash drives that contain digital files of Bryant’s U.S. Antarctic Service Expedition journals and photographs as well as narrations he recorded after the expedition. Also included is an unidentified reel of 16mm film.

The Charles Lofgren Papers, dated circa 1900s-1995 contains photographs, obituaries, articles, and news clippings regarding his personal life, his military career, his participation in Byrd Antarctic Expedition I (1928-1930) and his lecture tour that followed. Lofgren's lecture tour and numerous news clippings often focused on his relationship with his sledge dog, "Tom Pratt," who was born during the expedition. The 1989 material is a postage stamp commemorating Richard E. Byrd. This collection is comprised primarily of original materials that date to the time of the expedition or other events in Lofgren's life, with some photocopies of original materials created during Byrd Antarctic Expedition I that were produced at a later date.
