We have found a useful Italian publication, developed by Daniele Giacomini, which could be
defined as a Linux Encyclopedia. It provides a lot of useful information and it is
distributed for free under GPL licence. It is usually included in the Debian distribution.
The original Italian version can be read on-line from Daniele's site Appunti di Informatica Libera
We participate in the translation of the publication into English and you can download a tar file called Notes on free computing with the translated chapters.
If you know the language and want to participate in this translation project,
please send me e-mail.
