This series was originally filed by Mappin almost completely alphabetically by author, topic, or publisher/publication name. The textual material is essentially Mappin’s private antiquarian book collection and contains such items as early printed booklets, pamphlets, broadside sheets, clippings and handwritten notes. The graphic materials in this series are commercial ephemera consisting of receipts, letterheads, and telegraphs, and include some trade and political posters. Sound recordings include 45 rpm recordings of Joël Denis’s song Vas-Y-Cardinal and a speech by Quebec pliticain Jean-Guy Cardinal
The collection is almost entirely Canadiana focused, some of the more prominent file titles include: Bernard Amtmann, Imperial Federation, L'affaire Guibord, Richler, Mappin / Holden Affair, Lionel Groulx, Ignace Bourget, Henri Bourassa, Lawrence Lande, George Étienne Cartier, William Lyon Mackenzie King, the Eastern Townships and Montreal History.
