I reported earlier that I am working on a norwegian version of the book Free Culture by Lawrence Lessig. Progress is good, and yesterday I got a major contribution from Anders Hagen Jarmund completing chapter six. The source files as well as a PDF and EPUB version of this book are available from github.
I am happy to report that the draft for the first two chapters (preface, introduction) is complete, and three other chapters are also completely translated. This completes 26 percent of the number of strings (equivalent to paragraphs) in the book, and there is thus 74 percent left to translate. A graph of the progress is present at the bottom of the github project page. There is still room for more contributors. Get in touch or send github pull requests with fixes if you got time and are willing to help make this book make it to print. :)
The book translation framework could also be a good basis for other translations, if you want the book to be available in your language.
