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. 26 September 2016 will mark the third Anniversary of the passing of Clara Thomas – read more here.
We retrieve materials from storage Monday-Friday three times a day:
11:00 AM, 1:00 PM and 3:00 PM. Please call or email the archives ahead of time should you wish to have materials retrieved prior to your arrival.
The Archives will be closed Monday 04 September 2017 sorry for any inconvenience.
CLOSED on weekends, statutory holidays, and during the university holiday period (25 Dec. 2017 through 2 Jan. 2018 inclusive).
