# Search — Cyber Library

- HTML search: https://www.cyberlibrary.org/search/
- Programmatic search: use the catalog index and filter locally —
  `https://www.cyberlibrary.org/api/books/index.json`,
  then `https://www.cyberlibrary.org/api/books/lang/{lang}.json`.

The JSON shards contain title, author, language, slug and URL for every catalog entry, which is the
fastest way for an agent to resolve "where can I read <title>".
