Project Gutenberg API for books

A programmatic gateway to 70,000+ free public domain eBooks via OPDS feeds and machine-readable metadata.

The Project Gutenberg API ecosystem provides developers direct access to a massive library of cultural heritage, ranging from Mary Shelley's Frankenstein to the works of Frederick Douglass. By utilizing the Open Publication Distribution System (OPDS) and raw RDF/XML metadata dumps, engineers can integrate full-text downloads in EPUB, Kindle, and plain text formats. This infrastructure supports high-volume cataloging through mirrors like Gutendex, allowing for precise filtering by author, language, and subject matter without the overhead of manual scraping.
