Notes
- Source: Open Library data dumps (Internet Archive), authors + works, July 2026 snapshot, released under CC0.
- Deduplicated on normalized title + author pair — 3,128,493 duplicate entries removed from the raw works catalog.
- 6,496 entries with empty/junk titles excluded.
first_publish_dateandsubjectsare frequently empty — Open Library's community-contributed data is inconsistently populated at the work level, not every book has these fields filled in.- Author names reflect Open Library's linked author records; books without a resolvable author link show no value in that field.
