I wanted to read more classics, and the hardest part was finding them. Free, legal copies are spread across Project Gutenberg, Open Library / Internet Archive and LibriVox. Each has its own search, its own formats, and the same book shows up several times.

So I built Public Domain Book Finder : one API that searches all 3 at once and hands back one tidy list. It's the first of 3 reading APIs I'm building.

What it does

Endpoint What you get

GET /search One search across 78,000+ Gutenberg ebooks, Open Library's fully open scans and LibriVox audiobooks. Duplicates are merged.

GET /book/{id} Every free format for one book: EPUB, Kindle, HTML, plain text, or MP3 chapters for audiobooks.

GET /read/{id} The book as clean text: license pages removed, broken line wraps fixed, chapters listed, served page by page.

One search, 3 libraries
