At a talk by Ben Bederson at Webshop 2011, I learned about a fantastic resource: the International Children’s Digital Library. They have books available in full for free from all over the world in their original languages (like Hungarian, Mongolian, Arabic, German, etc.). In addition to offering these books in their original language, they’re also working on getting them translated by people who don’t necessarily speak the language of the original book. Intrigued? See how you can contribute. (This latter link is to the translation site, not the book site.)
