The Byrd Antarctic Expedition II Collection contains collected materials both from and about Byrd Antarctic Expedition II, some of which date before and after the Expedition. A candlestick from an expedition ship dates from 1884, and the rest of the collection dates from 1928 to 2010, with the bulk of materials dating between 1928 and 1935. The collection includes items such as correspondence from expedition members, artifacts from the United States Ship Bear and the expedition itself, a scrapbook, photocopies of the South Pole Radio News published by the expedition, an account of the trip to rescue Admiral Byrd from Advance Base by a crew member, advertisements by sponsors of the expedition, and postal covers.
