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.

Visiting CTASC

The reading room of the Clara Thomas Archives & Special Collections is closed since 14 January 2021 due to the lockdown ordered by the government of Ontario, but exceptions are being made for researchers with exceptional needs. If your research is of an urgent nature, please contact us by email at: archives@yorku.ca
