The Debian Administrator’s Handbook is available

We’re pleased to announce that (after 5 months of work) the Debian Administrator’s Handbook is now available, both as a beautiful 495-page paperback and as an ebook (PDF, EPUB, MOBI formats).

The paperback’s usual price is €44.90, but we decided to make a special deal for the launch. You can get it with a 10% discount until May 18th. Hurry up and get it from Lulu.com.

Download the ebookThe ebook is available for immediate download on the book’s website. There’s the PDF file corresponding to the printed book but also an EPUB version suitable for smartphones and ebook readers. You can also find a Mobipocket version for Kindle and other ebook readers that do not support EPUB (the open standard).

And of course, you can read it online.

Since the book is released under a set of free licenses (GPL-2+ / CC-BY-SA 3.0), it’s already available in Debian Unstable, just apt-get install debian-handbook. There’s also a git repository (git clone git://anonscm.debian.org/debian-handbook/debian-handbook.git) if you want to contribute.
