Where the library comes from.
OnlineBooks4Free is an index, not a publisher. We do not host the rights to these books — we surface them. Every title links back to a verifiable upstream source, and our DMCA takedown pipeline responds in a median of six hours. The catalog is built from four primary streams:
- Project Gutenberg
- The original public-domain library. We index its 70,000+ free EPUB and MOBI editions, refreshed daily.
- Open Library
- A non-profit catalog of borrowable and open-access editions, including modern titles with permissive licensing.
- Smashwords
- Indie-published titles made free by their authors — indexed with full genre and language metadata.
- 340+ author-direct programs
- Direct partnerships with independent authors offering time-windowed free promotions, surfaced as they go live.
Our open-source ingestion engine, OB4F-Crawler 4.1, scans 2,400 new sources a day. If a link breaks or a rightsholder asks for removal, the entry disappears within hours — not weeks.
