Considerable portions of the accession focus on Bull's role as a participant in the Scientific Committee on Antarctic Research (SCAR) Working Group on Glaciology, SCAR and the Council on Polar Research and National Science Foundation's (NSF) Division of Polar Programs.

Accession No. PA. 2000.0020, dated 2000-2002, contains recordings, administrative information and transcripts of an interview between Colin Bull and Brian Shoemaker of the American Polar Society. This interview took place on August 20, 2000, and covers Bull's participation in the British North Greenland Expedition (1952-1954), his work with American and New Zealand programs that worked in coordination with each other in the "Dry Valley" regions of Antarctica during the International Geophysical Year, and his work with the Institute of Polar Studies, later known as the Byrd Polar and Climate Research Center. Other major topics of the interview include a discussion of his expedition to the Sukkertoppen Ice Cap, Southwest Greenland with Fritz Loewe and his expedition and naming of Wright Valley during the first New Zealand Antarctica expedition of 1958-1959. Also included in the interview is his sponsorship of the first female field expedition the Antarctic in 1969, his role as chairman of the Scientific Committee on Antarctic Research Research (SCAR) Working Group on Geology, his opinions on the leadership and state of the Byrd Polar Research Center and the Institute of Arctic and Alpine Research (INSTAAR) and his experiences as a tourist in Antarctica under the guidance of the International Association of Antarctic Tour Operators (IAATO). Materials are arranged in the order created during the interview process. This interview was part of a series of polar oral histories sponsored by the American Polar Society and Ohio State University's Byrd Polar Research Center Archival Program, with funding from the National Science Foundation.

Accession No. PA.2011.0015, dated 1952-1956, contains 35mm negatives strips and a notebook. The negatives appear to be of the British North Greenland expedition of 1952-1954 that Bull participated in as a geophysicist. Within each folder, each individual strip is considered an item, which is numbered from top to bottom. The item number indicates the strip number. Many of the frames within a strip contain captions that Bull provided that give context to an individual frame. Underneath each frame is an edge number ranging from 00-41 that marks specific frames. Depending on their positioning within a strip, some edge numbers also have an A next to the number.
