Abstract
Western Libraries and Ingram Content Group worked together to establish a Patron Driven Acquisition (PDA) program that has been incorporated into the regular acquisitions workflow at Western. Some features of the program include: all titles selected for addition to the PDA collection are filtered through the approval profiles established by the librarians, the library’s holdings are uploaded to Ingram weekly so that duplicate titles are avoided, invoices for purchased PDA titles are sent weekly, and holdings for un-purchased and purchased PDA records are updated weekly. A PDA Working Group established the program at Western by meeting with collections librarians to assist with profile adjustments and ease concerns of how this method of acquisition would impact the collection. The Working Group is monitoring the program and gathering data to assess the impact of PDA. In addition to collecting information about titles loaded and titles purchased, an online survey to assess user response to e-books is continuing. Western and Ingram have continued to work together closely to ensure the program is successful and to make profile adjustments as necessary.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
