Hundreds of thousands of ebooks are available as free, legal EPUB downloads — public domain classics, open-access academic books, Creative Commons titles, and indie authors offering free books. Here are the best sources, organized by type.

Notable titles: Pride and Prejudice, Moby Dick, The Adventures of Huckleberry Finn, War and Peace, The Complete Works of Shakespeare.
EPUB quality: Good for text-only classics. Some older EPUB files may have basic formatting; newer ones include covers and clean structure.
