The fonds consists of a photocopy of the first of three volumes of Bobillier's diary describing his journey from France to the Yukon in 1939 and his subsequent missionary activities on behalf of the Oblates of Mary Immaculate in British Columbia and the Yukon.

The collection consists of correspondence, writings, sermons, manuscripts, subject files, scrapbooks, and other material which document the history of the Roman Catholic Church and its priests in British Columbia, Washington, and Oregon.
