The Debian Administrator’s HandBook is out11/05/2012 por (orig)
The Debian Administrator’s HandBook is a book written by Raphaël Hertzog and Roland Mas, two Debian Developers. It was originally written in french, and now it has been translated into english.
You can browse the online version for free, or you can pay for it and get the paperback, or e-book version (in 3 formats: PDF, EPUB, Mobipocket)
The book source is also available for anyone who wants to contribute to the project.
With the book source available, we can expect a brazilian portuguese translation someday (as some people already commented on Raphaël’s announcement). As well as translations to other languages.
