Fonds consists of the textual records, n.d., 1857-1991, in the following series: Mail and Empire and the Globe, Maclean's Magazine, the National Film Board, the Department of External Affairs, Victoria Daily Times, Personal and Memoirs. The order of these series chronologically parallels the pattern of Irwin's life and career, except for the Personal series, which encompasses his entire life. Various sub-series indicate major activities, interest or stages in Irwin's career. The material in this fonds has been arranged alphabetically, retaining as closely as possible the original order. It should be noted that the date range for each series is quite broad, reflecting the fact that Irwin added research notes to many of the existing files.
