The sub-subseries consists of twenty miscellaneous geological maps, charts, and plans of Egypt, Sinai Peninsula, Rome, Manitoba, British Columbia, Northwest Territories, Newfoundland, New Brunswick, the eastern part of British North America, Snake River, Montana, Wyoming, Wisconsin, St. Lawrence River, Cumberland Coal Field, North Pole, and Pictou Harbour. Maps are both printed and hand-drawn.

Sub-sub-series consists of active office files, filed by subject, related to Dr. Penfield's writings and travels. (C/SW = Correspondence/Subjects Writing)

Sub-series consists of 32 cassettes, recorded between 1955 and the end of the 1970s, created to accompany the Cree language course developed by C. Douglas Ellis. First published in 1962, the course was revised and reissued in 3 volumes in 2000. Tapes correspond to lessons in Spoken Cree: Level I and Spoken Cree: Level II. Instruction is in the N-Dialect, or Swampy Cree, spoken on the west coast of James Bay. Guidelines for applying lessons to the L-Dialect are given in audio.

Sub-series consists of lessons recorded on 35 cassettes with spine label Cree A3 and 29 cassettes labeled Cree A5 ; These correspond to the textbooks "Cours de Cris: Première Degré," and "Cours de Cris: Deuxième Degré." Both texts are authored by Louis-Philippe Vaillancourt, and published by Les Presses de l’Université du Quebéc.
The focus of instruction is Cree as spoken on the east coast of James Bay, and lessons are presented with the participation of residents from Wemindji and Eastmain. Lessons on the A3 cassettes center on building a basic vocabulary through listening and repetition, lessons on the A5 cassettes concentrate on transitive and intransitive verbs. The sub-series also contains one folder of plastic sleeves holding 25 compact discs. Discs are labeled to correspond to audio cassettes in the A3 series, likely from an earlier format transfer project.

Sub-subseries consists of manuscript essays and addresses on scientific subjects falling into four categories: (1) popular lectures, not only on geology, but also on biology, entomology, physics, archaeology and even linguistics; (2) mining, particularly of Nova Scotia coal, with some reports and maps; (3) geology, largely of Nova Scotia, and (4) palaeontology (approximately 72 cm). Some of the materials in sub-subseries are drafts of works later published, and these papers also contain 80 cm of Dawson's printed books and articles.

Sub-subseries consists of approximately ten of Dawson's scientific notebooks (box 29). Most are pocket memoranda, but some are more discursive, such as a notebook on Nova Scotia geology and one of geological notes from the 1860s and 1870s. Three scrapbooks bear directly on science: "Scientific Scraps" is largely pictorial material; "Scraps relating to science and religion", despite its title, is mostly Dawson's published articles on geology, education, and travel (boxes 39-40); finally, a scrapbook of clippings programmes and photographs serves as a souvenir of Dawson's presidential meeting of the BAAS in Birmingham, 1886 (box 77).

The Fold-out Valentines sub-subseries consists of 33 cards that feature some sort of interactive component. This may include flaps that open to reveal hidden messages, or pop-up cards that can be folded out to make a free-standing three-dimensional image.

The Stationer's Scraps sub-subseries is comprised of 15 scraps of card. These consist of individual pieces of cutout card that have either fallen off existing cards, or which were meant to be used by a cardmaker in the fabrication of greeting cards. They are excellent examples of the small details that were included in the decoration of cards during manufacturing.

The Sentimental Valentines sub-subseries consists of cards, handmade or manufactured, in which a long, sentimental poem is the main feature. The cards range in terms of format and style. They may be elaborately decorated by hand with several materials, or simple printed on cardstock. They are usually illustrated with allegorical images or stock illustrations of couples, mythology or landscapes. Some of the cards have handwritten messages professing one’s love for the recipient. They are excellent examples of Victorian sentimentality and 19th century poetic verse.

The Scrapbooks sub-subseries contains a full scrapbook of publisher’s samples, as well as individual scrapbook pages with multiple attached cards that have been extracted from a book. The cards in these scrapbook pages usually include a bulk price per dozen and instructions from the publishers, such as to specify the desired message inside the card. There are some pages that may be from a personal scrapbook as the cards pasted inside it are signed by a sender.
