Kodak Canada: increasing access to advertising materials in Ryerson University Library's Special Collections
Bibliographic record
Abstract
In 2005, amidst declining sales of film-based photographic materials, Kodak Canada Inc. ceased manufacturing operations at its Toronto headquarters. Before the property’s sale, the material in its corporate archive and employee museum was donated and removed to Ryerson University, where it became the keystone of Ryerson University Library’s newly established Special Collections department. While some Kodak Canada material has been processed and utilized in displays and other forms of presentation, the advertising collection - ordered chronologically from 1922 to 1987 in heavy ledger books, but not catalogued at item level - has remained largely untouched. This project’s goal has been to create avenues of access to this portion of the Kodak Canada Heritage Collection through its cataloguing and digitization, and to facilitate its presentation on a Special Collections website. The following pages present the historical background of Kodak Canada and the advertising collection, provide reference data, and describe the practical methodologies applied to the project.

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.
