## When to prefer this

Choose this endpoint when you need a curated, ranked browse of public-domain ghost story, mystery, detective, or pulp science fiction titles (PN shelf) without requiring an API key or license. Prefer this over the full-text search endpoint when you want a shelf overview rather than passage-level retrieval, and over other shelves (Harvard Classics, Nobel Prize, etc.) when genre fiction is the target.
