The Matthew R. Isenburg collection: the dissemination of information on a private photographic collection, 1972 ‐ 2012
Bibliographic record
Abstract
This thesis examines how the Matthew R. Isenburg Collection of nineteenth‐century photography and photographica, assembled between 1972 and 2012, was used by researchers, scholars, and photography‐enthusiasts, and how information about it was disseminated to the public, prior to its sale to the Archive of Modern Conflict, Toronto, in 2012. The private collection focused on five areas from early photography (1830s – 1860s): the Southworth & Hawes photography studio (Boston, 1843 – 1863), images of and information about the California Gold Rush (1848 – 1855), photographic technology (including cameras, lenses, and studio equipment), daguerreotype and ambrotype cases, and nineteenth-‐century literature (featuring technical manuals and sales catalogues). This thesis features a literature survey, documentation of how Isenburg displayed his collection within his home, a description of the experience of visiting his collection, an annotated bibliography of publications that feature the collection, and an analytical chapter describing how the reputation of the collector and collection evolved.

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.
