BarCampMontreal is a good place to discover some great projects. Librivox is one of them, simple but very useful for the society. In a short interview, Hugh McGuire, founder of Librivox, presented us this unique digital library of free public domain audiobooks, read only by volunteers.
As Hugh explained it, they don’t need money (very rare at BarCamp). Same as Wikipedia, they just want your contribution to read, listen and organize new open-source audiobooks. Make your choice amongs over 1,400 books in 23 different languages.
