Abstract
Nova et accurata Terrae Marisq. Sphaera, denuo recognita et correcta à Gulielmo Blaeu. Amsterdam: Willem Janszoon Blaeu, 1606 (1621). 1 globe : hand coloured; 13.5 cm. in diameter. This globe by Willem Jansz Blaeu (1571-1638) was originally published in 1606 but has been revised to include the discoveries at the tip of South America in 1616 by the Dutchmen Willem Schouten (active 1590–1618) and Jacob Le Maire (1585–1616). The globe forms a pair with the celestial globe at Maps G.6.a. This model was created for a 2020 British Library project in partnershp with Cyreal to digitise globes from its historic map collection.

How this classification was reachedexpand
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.
