Comparing Safari Tech Books Online and Books24х7 E-book Collections: A Case Study from the University of British Columbia Library.
Bibliographic record
Abstract
Most academic libraries are seeking to provide electronic access to the very dynamic and changing field of technology related material. Safari Tech Books Online and Books24x7 are the major e-book collections in this area. We compared the Safari Tech Books Online and Books24x7 e-book packages as to their usefulness for the University of British Columbia Library, second largest academic library in Canada. In our sample, we found that Books24x7 had more titles to offer (25% more); the overlap between the collections was relatively small (13-16%) and publishers varied considerably; and although there were no major differences in the "usefulness" measures of the titles in the two packages (Amazon.com ratings, WorldCat holdings and Reviews.com reviews were quite similar for both packages), O'Reilly titles, available only through Safari Tech Books Online, were held by a slightly higher number of libraries worldwide. We conclude that in order to have comprehensive coverage of this constantly changing area of knowledge, a large research academic library needs to subscribe to both collections. If subscribing to both collections is not an option, we recommend selecting a package based on the pricing that the library can negotiate with ProQuest, the vendor of both products, since the collections are complimentary in their nature.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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, unvalidatedLabeled directly by 2 models reading the full record.
