There is an enormous library of books you can download and keep, completely legally and for free. Classic literature, scholarly monographs, textbooks, children's stories and tens of thousands of audiobooks are all out there. Knowing which books are free — and why — keeps you on the right side of copyright.
What “free” really means
- Public domain — the copyright has expired (generally for works published long enough ago), so anyone can read, share or adapt them freely. This is where most classics live.
- Openly licensed — the author chose a license (like Creative Commons) that permits free sharing, common for open-access academic books.
- Free to borrow — still in copyright, but a library lends you a copy for a limited time, just like a physical book.
- Free sample — a preview of a paid book; useful to try before you buy, but not the whole book.
Where the free ebooks are
- Project Gutenberg — over 70,000 public-domain ebooks, carefully digitized, in EPUB and plain text.
- Standard Ebooks — public-domain classics, beautifully typeset and proofread, free to download.
- Open Library & the Internet Archive — millions of scanned books, many free to read or borrow.
- Directory of Open Access Books (DOAB) — thousands of peer-reviewed, openly licensed academic books.
- Google Books — free full view for public-domain titles, with previews and official buy links for the rest.
Where the free audiobooks are
- LibriVox — public-domain books read aloud by volunteers; completely free, downloadable as MP3.
- The Internet Archive — a huge collection of free audio, including LibriVox recordings and historical audio.
- Your public library — apps like Libby or Hoopla let you borrow current audiobooks free with a library card.
Ebook and audio formats, briefly
EPUB is the standard ebook format — it reflows to fit any screen and works in almost every reader app. PDF keeps a fixed page layout, best for textbooks and documents you want to look exactly as printed. For audio, MP3 or M4B files play everywhere. If a book is offered in several formats, EPUB is usually the most comfortable to read on a phone.
PaperFinder's Books tab searches all of these at once — Google Books, Open Library, Project Gutenberg, DOAB, LibriVox and the Internet Archive. Free and public-domain titles can be read or downloaded (and played in the built-in reader); paid books link to the official store. We never host pirated files.
