Series consists of research subject files accumulated by Audrey L'Heureux over the course of her journalism and writing careers, with material collected between 1960 and 2005. L'Heureux arranged her subject files alphabetically; the files were organized by topics such as specific communities, people, historical events, industries, and geographic features. The files consist of reproductions from secondary sources such as periodicals and publications, as well as reproductions from primary sources from other archives (including copy prints of historical photographs). The files also include newspaper clippings, maps, correspondence, books, postcards, and journal articles. The material in the files covers a date range of 1860 to 2005, but material from earlier dates are reproductions only.
The content of the research subject files spans Northern and Central British Columbia, with a focus on the communities of Smithers, Prince George, and Vanderhoof where L'Heureux lived. L'Heureux's research subject files cover the transitional phases in British Columbia’s history, including natural resource extraction, the impact of the railways, industrialization, land survey, and interactions with Indigenous communities. Other topics reflect changes to British Columbia post-industrialization, including collected research material on fisheries, telegraph lines, law enforcement, and historic sites. L’Heureux also collected research material about the people who shaped the province and local community figures in Northern and Central British Columbia.
