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 open by appointment only. Appointments are available Tuesday to Friday, from 10 a.m. to 12 noon and from 1 p.m. to 4 p.m.

To book an appointment, email archives@yorku.ca at least three working days prior to your proposed visit. Please include a list of records or books you wish to consult. You will then receive an email confirming your appointment time. Appointments are available on a first-come, first-served basis.

Only one researcher may access the reading room at a time. You must always wear a protective face covering over your mouth, nose and chin in Scott Library. Please do not come to Scott Library without a confirmed appointment. Appointments cannot be made on the spot.

You must show photo identification each time you access the reading room.
