Fonds consists of records documenting the administration of TRIUMF and includes Board of Management minutes and meeting dockets, committee minutes, and reports. Also included are reports and published proposals documenting the origins and ongoing development of TRIUMF. The records are arranged in the following series: Board of Management, Finance Committee, Audit Committee, and Reports.

The fonds consists of Craddock’s professional papers in the form of textual records (including correspondence, reports, minutes, course materials, interviews), published materials, technical research notes, presentation slides and reference materials. The papers primarily chronicle Craddock’s work and role at TRIUMF, particularly TRIUMF’s attempt to build a Kaon Factory particle accelerator. Many other aspects of TRUMF are documented in these papers, including- administration, various committees, workshops, published reports and research, various particle physics projects, physics reference files, and collaborations with other organizations. Craddock’s work on recording TRIUMF’s origins and history is also represented.
Outside of Craddock’s involvement with TRIUMF, other professional papers reflect his teaching career, talks, presentations, correspondence with colleagues, graduate students, and the public.
