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 Urbain J. Kinet Slides and Photographs Primarily of Landscapes and Wildlife in Antarctica and New Zealand, dated 1965-1969, contain color slides and photographs taken by Urbain J. Kinet. Kinet mostly shot the slides and photographs while assisting with entomological and geological research in Antarctica. The images mainly show landscapes and physical features of different locations in Antarctica, as well as images of Antarctic wildlife. Also included are color slides and photographs taken by Kinet in New Zealand and possibly other places. Many of the slides have captions written on them. The folder titles and dates are based on these captions and any additional information available from the Polar Rock Repository inventory of digitized slides. The photographs are dated from 1968-1969, which is when the prints were developed, but they were likely taken in Antarctica or New Zealand from 1965-1966.
