The collection consists of 10 ink manuscript maps and plans on paper, some hand-coloured, depicting the earliest settlements and fortifications at Montreal and Quebec City. The earliest dated document is a plan of the fort of Quebec and is dated 1635. The earliest document in the collection depicting Montreal is believed to date back to 1642. The maps and plans were prepared by Jean Bourdon, seigneur and surveyor for the French colony. Included in the collection is a plan of the earliest Fort Richelieu of which nothing had previously been known. There are also detail drawings of riverside fortifications, probably near Montreal.

The Roger Doucet Collection consists of over 1000 pieces of sheet music (including scores), 45 manuscripts, and one scrapbook containing photographs and newspaper clippings related to his career as the singer of “O Canada” during professional sports games.

Collection consists of 57 illustrations of birds, eggs, snakes, and plants by James Forbes chiefly to illustrate his work "Oriental Memoirs," published in four volumes between 1813 and 1815. The majority of the illustrations are either engraved or hand-drawn and then coloured, and have been cut out and mounted on paper. In many cases, a background has been drawn in and coloured or partially coloured. Approximately thirty of the images depict tropical birds, many from the Indian subcontinent, as well as some from Brazil and Australia. A number of these drawings also feature insects, particularly butterflies, and trees and flowers. Fifteen drawings depict bird eggs, including many of forest birds. The images generally contain captions by Forbes or a contemporary, identifying the subject of the drawing. Some birds are unidentified. Numerous drawings also contain species identifications or annotations in pencil by Henry Mousely, librarian of the Blacker Wood Library at McGill University during the 1920s and 1930s. These drawings are tentatively dated to approximately 1811. A note on one drawing indicates that it was originally based on drawings created during Forbes's voyages during the 1780s, then recopied in 1811. Items 44 through 57 depict snakes and reptiles and are tentatively dated to between approximately 1811 and 1818, based on a small number of drawings which are signed and dated. Many of these drawings of snakes and reptiles feature as plates in Patrick Russell's "A Continuation of an Account of Indian Serpents: Containing Descriptions and Figures, from Specimens and Drawings" (1801).

The collection consists of autographed signed letters from multiple senders, representing authors, artists, politicians, and other figures from Canada and Europe. The letters were accumulated by the Rare Books and Special Collections unit of the McGill Library over many years and assembled into the collection.

Collection consists of two commercial documents bound together that record the exchange of goods between John Taylor of Queensferry, Scotland, and William Taylor of Montreal. The first document is a one-page list of unsold goods, entitled "List of goods on Mr Wm Taylors [sic] hands remaining unsold as per account sales, sent 11th October 1787 - tho' shipt per the Elizabeth, A. Syme April 1786." It lists a variety of goods, including fabrics, horse tack, carpet, and beer, along with their values. The second document is an inventory of a shipment, entitled "Invoice of a cargo of goods sent per the Elizabeth, Captn A. Syme, to be sold on my account by Mr William Taylor, Merchant Montreal, Queensferry, March 16, 1787." The invoice lists goods - such as fabrics, accessories, tools, household goods, beer and wine, and sugar - as well as insurance, carriage, and customhouse fees.

The general orders contain reports detailing the sequence of events leading up to and during the fires, as well as the actions of the soldiers fighting the fires, and the damaged caused by the flames. The orders also include messages of thanks to the soldiers and their commanding officers from community leaders. Major-General James A.
