Clara Thomas Archives & Special Collections

The Clara Thomas Archives and Special Collections collects manuscript, rare book and primary source materials to support research and learning by the university’s faculty, students, and a community of international scholars. We are strong in the areas of Canadian history, fine arts (design, photography, music, film, theatre), philosophy, environmental history, and sexual diversity. We welcome all researchers and visitors; however, a visit to the Clara Thomas Archives and Special Collections (CTASC) is a different experience from visiting another department or section of the library.
