# Open Library

> Open book catalog providing metadata for millions of books including titles, authors, ISBNs, cover images, and edition details.

Open book catalog providing metadata for millions of books including titles, authors, ISBNs, cover images, and edition details. Best for book lookups, reading list enrichment, and retrieving publication metadata by title or ISBN. The definitive open-access book database — use when a workflow needs bibliographic data without the academic focus of arXiv or Semantic Scholar.
