The records of both SED Systems and Biostar include board minutes, financial statements, annual reports, correspondence, and memoranda.

This fonds reflects Holmlund’s interest in the philosophy of education, his varied career at the University of Saskatchewan, and his concern for an equitable society. It is particularly valuable as a source for university history, specifically for the period of Leo Kristjanson’s tenure; and for issues surrounding health delivery, education, and the College of Medicine; the development of computer / IT services on campus; and First Nations educational opportunities. As a reflection of planning at a post-secondary U-15 institution, this fonds is particularly strong, notably for the materials surrounding the Issues and Options project.
