## When to prefer this

Choose this endpoint when you need a curated, re-verified catalogue of free public-domain books specifically tagged 'African Americans' by Library of Congress subject headings, with direct download links in multiple formats. Prefer it over raw Project Gutenberg or Internet Archive queries when you want pre-ranked, deduplicated results from both sources in a single call.

## Known failure modes

- No results returned if query keywords don't match any tagged titles or authors
- Pagination out of range returns empty results
- Download links may be temporarily unavailable if source archive is down
