The Carl Hoffmeyer Scrapbook on Operation Deep Freeze I, dated 1955-1957, contains newspaper clippings about the United States’ exploration and research progress during Operation Deep Freeze I. Newspaper clippings about the exploration of Antarctica by the United Kingdom, Russia, New Zealand, and Japan are also included in the scrapbook. Hoffmeyer divided the scrapbook into several sections; the sections are divided by articles that define the purpose of Operation Deep Freeze, the equipment used during the expedition, and the operation’s progress. The last part of the scrapbook has newspaper clippings related to the International Geophysical Year and the death of Admiral Richard E. Byrd.

DenHartog Oral History, dated 1981-2009, contains audio recordings, administrative information, and transcripts of the interview between DenHartog and Brian Shoemaker of the American Polar Society conducted on October 22, 2002. The collection also contains personal notes by DenHartog about his life, which were created starting in 1981, and correspondence from 2009 about the transcripts of the interview. This interview was a part of a series of polar oral histories sponsored by American Polar Society and Ohio State University's Byrd Polar Research Center Archival Program, with funding from the National Science Foundation. Major topics that DenHartog discussed include going to Antarctica during the International Geophysical Year (1957-1958), his experiences during the Ross Ice Shelf Traverse and the Victoria Land Traverse, the story of how Albert (Bert) Crary needed to be rescued after the piece of ice that he was working on split off into the water, spending the winter at Little America V, working at the second Arctic Research Laboratory Ice Station (ARLIS II), which was a station installed on a floating ice island off the coast of Point Barrow, Alaska, working for the University of Wisconsin Geophysical and Polar Research Center in Alaska and Antarctica, and working aboard the SS Manhattan in the Northwest Passage.
