The Mary-Jacques Cambay Collection is the result of Mary-Jacques Cambay‘s research into stained-glass in Quebec, and the contributions of artists working in stained-glass to the Province's artistic heritage. The collection documents stained-glass windows existing in Quebec churches during the 1970s and 1980s. It also includes information pertaining to select churches. In addition, the collection documents the works of a number of stained glass artists, including Guido Nincheri, Charles William Kelsey, and Flavien St. Pierre, and the stained-glass studio "Canadian Pittsburgh Industries Limited" (C.P.I.). Importantly, it contains oral history interviews conducted by Cambay with artists working in stained glass.
The Mary-Jacques Cambay collection is composed mostly of photographic materials in form of prints and slides, but also audio cassettes and textual records. As textual materials, the collection consists in pamphlets, newspaper clippings, correspondence, extracts from reference works, and handwritten notes. An index of Quebec churches with stained glass windows completes the collection.
