This library prioritizes causes, mechanisms of degeneration, prevention, disease modification, and durable restoration. Symptom-management research stays in the collection because useful connections can cross research boundaries.
What is working
Five metadata collectors, multilingual discovery, preserved source responses, identifier-based linking, authorized export imports, permitted PMC article text, PDF/text reading guides, a glossary, source-linked plain-English examples, a durable reading queue and an early searchable findings pilot.
What comes next
Broader licensed access, more full text, trial and dataset links, historical scans, expert review, and broader structured extraction. Study and participant overlap must be assessed before reports can be counted as independent evidence.
What a tag means
Tags are transparent keyword candidates, not an assessment of causality, treatment efficacy, or study quality. A passage saying an approach failed may receive the same topic tag as one reporting success. Open a record to see the words that matched.
Collection boundaries
This release contains bounded API samples. Absence from the catalog means only that material has not been collected here. Some permitted full texts have been acquired; most records still contain metadata or abstracts. Participant-level data have not been acquired. Original abstract text may carry its own reuse restrictions.
