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.

Series consists chiefly of 38 manuscripts related to the North West Company. Among the Masson manuscripts there are other series of letters; as well as journals kept by North-Westers and various business documents. Some of this material exists as originals; others are contemporary copies - the George Keith letters for example are contemporary copies on paper watermarked 1827. The collection also includes some duplicate texts - contemporary copies or later nineteenth-century copies that in some cases represent edited versions of the texts. Samuel Wilcocke's account of the death of Benjamin Frobisher exists in a draft original (or contemporary copy) and in a late nineteenth-century clean copy. Of course Benjamin Frobisher did not die in the dramatic circumstances as recorded by Wilcocke, but peacefully in Quebec City in 1821.

Series consists of approximately 300 culinary, medical, and household recipes dating from roughly the 1780s through the 1850s. Recipes are handwritten in multiple late 18th- and early 19th-century hands on papers of varying sizes, including many small fragments. Medical recipes consist of doctors' prescriptions and various formulae for making and using medicines. Household recipes and instructions are found for products such as polishes, cleaning solutions, and dyes, and activities such as clothes washing. Culinary recipes, the largest category of recipes, are found for a variety of dishes and ingredients, including multiple recipes for puddings, wines, jellies, cakes, gingerbreads, vinegars, biscuits, yeast, pickled dishes, and preserved fruits.
Many contain attributions by the recipe writers, listing the creator or provenance of the recipe. Some recipes also feature names of addressees. Many of these are addressed to Mrs. Warde and appear to be recipes that were either sent to her or solicited by her from friends and acquaintances. One document that postdates the rest of the items in the series is a bill (1950) addressed to Mrs. Warde-Aldam (MSG 1231-2-9).
