  • The Ontario government has issued a stay-at-home order. Libraries are closed to all non-required use.
  • Libraries continue to operate contactless book lockers and select services. Those who have exceptional needs or require access to study space, printing, computers, etc., can contact askusyul@yorku.ca for assistance. The screening checklist must be completed before coming to campus.
  • Scott Library will be without power on May 17 from 10:00 p.m. to 6:00 a.m. the next morning to complete necessary maintenance on the electrical system. As servers hosted in the library will be affected by the outage, some services may be disrupted, including YorkSpace, York University Digital Library, York Digital Journals, Scalar, Pressbooks and others.

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.
