Rehousing, Digitizing, and Cataloguing the J.M. Baillargeon Lantern Slide Collection: Capturing 19th Century Canada in Magic Lanterns
Bibliographic record
Abstract
In partnership with the special collections at Toronto Metropolitan University Libraries, this applied thesis investigates preservation techniques for the J.M. Baillargeon lantern slide collection. The Photographic Historical Society of Canada (PHSC) received a collection of lantern slides from Rev. Joseph Marc Baillargeon, including his commercial slides mainly labeled "Canadian Pacific Railway" (CPR) or "Canadian National Railway" (CNR). Baillargeon's images depict his diverse interests, from sportsmanship to flora, with a focus on rural areas in Ontario, Quebec, and Western Canada. It applies three preservation techniques—rehousing digitization and item-level cataloguing—to the 316 hand-coloured black and white commercial lantern slides from the collection. In addition, it proposes a preservation plan in order to improve future care and facilitate easy access for researchers and scholars to the collection.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
