The Barney Bradley Papers date from 2009. While serving on Byrd Antarctic Expedition II in 1933-1934, Barney Bradley kept a diary, took photographs, and collected newspaper clippings and a crew roster from the expedition. In 2009, Bradley's son Michael made reproductions of these items, including photocopies of the newspaper clippings and crew roster, reprints of photographs, and a typed transcript of the original diary. These reproductions were donated to the Polar Archives by Michael, and make up the Barney Bradley Papers; the Bradley family kept the original 1933-1934 items in their possession.

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.
