Abstract
The rising cost of textbooks for students has been highlighted as a major concern in higher education, particularly in the US and Canada. Less has been reported, however, about the costs of textbooks outside of North America, including in Europe. We address this gap in the knowledge through a case study of one Irish higher education institution, focusing on the cost, accessibility, and licensing of textbooks. We report here on an investigation of textbook prices drawing from an official college course catalog containing several thousand books. We detail how we sought to determine metadata of these books including: the formats they are available in, whether they are in the public domain, and the retail prices. We explain how we used methods to automatically determine textbook costs using Google Books API and make our code and dataset publicly available.

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
