The collection consists of documents amassed by Roderick Mackenzie. 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.

Collection includes a scrapbook created by Maude Lilian Bremner during her time in South Africa as a teacher to Boer children in refugee camps, as well as other related loose clippings and ephemera. The scrapbook contains newspaper clippings, postcards, and other ephemera tipped in. Many of the clippings are articles reprinting letters written home by Bremner and other volunteer teachers in her contingent. Collection also includes a published Memorandum respecting the engagement of teachers for the refugee camps in South Africa.

Collection contains two financial documents related to McGill College. The first is a memorandum between the College and its creditors in which the College agrees to pay out dividends and pay in installments towards the balance of the College's debt. It is signed by the individual creditors as well as by the principal of McGill College, Edmund A. Meredith. The memorandum contains a list of creditors of McGill College with their names and occupations listed, including William Lyman, druggist, Robert Abraham, printer, John Keller, merchant, and many others. A note dated 24 March 1847 with a response from representatives of the creditors is pasted on. The second document is a ledger sheet dated from 1844 to 1847 with the caption: "The Directors of McGill College to Joseph Hitchens."

These are various business papers of Simon McTavish and include partnership agreements with William and Duncan McGillivray, William Hallowell, Roderick McKenzie, Angus Shaw and James Hallowell, 1806 and drafts of agreement for seven years between McTavish, Frobisher and Company and John Fraser of London, Simon McGillivray and John Tullon, 1805.

Collection consists of menus acquired individually by the library. Menus date back to 1877, but most of the menus are twentieth century. The bulk of menus are from Montreal-area restaurants and hotels, representing French, Quebecois, and other styles of cuisine such as Indian. Some menus are from specific dinners given at hotels, special events, or in honour of dignitaries, such as a dinner for Edward, Prince of Wales, 1919. A subset of menus relate specifically to travel and include train dining car menus and steamship menus.

Containing a significant amount of information concerning the latter years of Napoleon’s reign (ca. 1810-1815), this carton would be of particular interest to researchers interested in the Armistice at Pleswitz and the diplomatic negotiations surrounding the Treaty of Fontainebleau. Diplomatic dealings between Metternich and Caulaincourt are particularly heavily represented. The dense copies of diplomatic correspondence could be of considerable interest to researchers with a sharp focus on the day-to-day negotiations concerning Pleswitz and Fontainebleau.

In addition, Folder 17 contains an unpublished description of the post-Waterloo Hundred Days by Caulaincourt. Therein, Caulaincourt recounts a broad narrative from the defeat at Waterloo to the Bourbon Restoration, including important descriptions of the question of succession and of the final push made by the Allies to restore Louis XVIII to the throne.

Collection consists of an illustrated manuscript containing a map and brief guidebook to Paris landmarks, created by Nicole Allardet probably during the 1940s or 1950s. The item is inscribed to Vivienne Horne. A folded booklet on heavy grey paper, the guidebook contains twelve panels, ten of which feature a gouache illustrated vignette of a Paris landmark and a short handwritten description in white. The landmarks include the Jardin du Luxembourg, Opera House, Eiffel Tower, the river Seine, the Bois de Vincennes, Notre-Dame de Paris, the Jardin des Tuileries, the Champs-Élysées, Montmartre, and the Luxor Obelisk in the Place de la Concorde. In the centermost two panels is a simple map of Paris showing the landmarks depicted.

The collection was assembled by the Rare Book Department at McGill to group a number of anonymous poetry collections and verse miscellanies dating from roughly the long eighteenth century. These include: a volume written around 1700 containing Milton's Comus and other poems, largely elegiac; a group of 38 original poems from 1774; satires of Cambridge personalities by an undergraduate (1795-1800); a volume of poems bound in vellum written in various hands by George Colin Campbell, Miss Flaxman, Mrs. A. M. Keith, Bernard Bolton, George Tucker and others, with sketches (1817); and Lady Murray's poetry commonplace-book (approximately 1820) containing poems by celebrated authors and some original pieces.
