Fonds consists of materials related to David Measday from his time as a graduate student at Oxford to his post-retirement work at UBC. The fonds primarily include material regarding his research, academic writings, and administrative duties at the University of British Columbia. Additionally, reports arise from various international, governmental, and non-governmental organizations with which Measday had some association. Organizational records include materials for the development of TRIUMF. There is also a small amount of teaching material from lectures and physics courses taught by Measday. Material is organized into series based on intuitional association, most of which is from Measday’s time working at UBC and TRIUMF.

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.
