The fonds consists of lecture and research notes chiefly in the field of theoretical and experimental investigations in physical electronics.

The fonds consist of research and lecture notes, records of experiments, logbooks, calculations, draft manuscript for a book "On the Hypotheses Which Underlie Physics," and various journals and off-prints.

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.
