Placed on permanent loan with University of Victoria Libraries in 1976, this unique collection is the legacy of the Catholic Diocese of Victoria and bears the name of its founder, the second bishop of Victoria, Charles John Seghers. The 1,431 titles comprising the Seghers Collection attest to the Roman Catholic presence on Vancouver Island, documenting the Catholic doctrine and identity brought to the missions and communities of the Pacific Northwest. This essay explores the bibliographic history of the Seghers Collection, its spiritual and religious significance within the Catholic tradition, and its original owner, Charles John Seghers.
