I am asking for help and volunteers to make Mastering Bitcoin available in as many languages as possible. As you may know, I worked out a deal with my publisher (O'Reilly Media) to license the 1st edition of the book under a Creative Commons open-source license (specifically CC-BY-SA). This makes it possible to use the entire book in any way, mashup, edit, revise etc. I also allows independent translations from volunteers.
I have a project on Transifex, a translation site, for translating the book. A team of more than 200 volunteers has already completed translations in Japanese, Hungarian and Korean. We are above 80% done in Spanish, French, Italian and Brazilian Portuguese. There are 31 languages in total which need volunteers to complete.

Not only can you help educate thousands of developers on bitcoin, you can learn bitcoin in more depth by helping with this effort!
Join transifex and the Mastering Bitcoin to start contributing to the translation of your native language:
