Abstract
In the fall of 2010, a grant of $36,000 allowed Portland Community College Library to purchase and place on reserve a copy of every required text at one of its campuses. A smaller college “center” also placed all required texts on reserve. The program was very popular with students and parts of the reserve collection received heavy use. Compared to the previous fall term, overall use of reserves at the Cascade Campus library rose 35%, and the Southeast Center collection saw an increase of 110%. However, use of the collection was unevenly distributed, with 26% of the books having more than 11 uses that quarter, but a troubling number (37%) receiving no checkouts at all. An analysis of the data suggests several ways that books with 11 or more uses per quarter could be increased to over 70%. These are to purchase and process books in a timely manner, to adjust loan periods for some items, or to purchase texts only for courses with multiple sections. Use numbers compiled over the following 8 quarters show that textbooks purchased and placed on reserve will be used for several successive terms. Keywords: Library Reserves, Textbooks, Sustainability, Course Reserves, Community College Libraries.

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.
