Journal articles written by geologists and polar scientists, and a copy of the research paper Passel wrote with Paul Siple, another scientist on United States Antarctic Service Expedition, are also included in this collection. This collection also contains VHS videocassettes recordings of speaking engagements where Passel spoke about his experiences in Antarctica, as well as an oral history interview on audiocassette where he discussed his time on the United States Antarctic Service Expedition. The original VHS videocassettes were created between 1996 and 2004. DVD copies of the VHS videocassettes were created in 2012.
