A keyless catalog API for WolneLektury.pl, Poland's free digital library of public-domain and open-licensed literature. Query books, authors, genres and literary epochs, each returning tidy JSON with cover art, colors and download links. The full book list is a multi-megabyte payload, so lean on the smaller collection endpoints for quick calls.
