You can find free audio for almost all of our books on the internet, on sites like litteratureaudio.com. They have works from classic authors like Maupassant or Zola.
For your ease we compiled the free audio and offer them for free on our site as well. Check out all the mp3s now under the French collection, click the link above.
We will add more soon. For example, the audio for the book Arsene Lupin - Gentleman-Cambrioleur you still have to get here: http://www.litteratureaudio.com/livre-audio-gratuit-mp3/leblanc-maurice-arsene-lupin-gentleman-cambrioleur.html
With your support we can create more interlinear language books and for books that have no free audio we will have voice overs created. So go on our site and buy books, or find paperback versions here on Amazon!
