Hi, There is also: In Libro Veritas (http://www.inlibroveritas.net) a small editor for open content license books (Licence Art Libre<http://artlibre.org/>, Creative Commons <http://fr.creativecommons.org/>, GFDL<http://www.gnu.org/copyleft/fdl.html>). You can get the books in pdf or on paper for a price depending on the quality of the paper (new or recycled) and on the number of pages ( http://www.inlibroveritas.net/presentation_livres.php). They will give 10% back as royalties, I don't know but we could use it to sponsor some opensource projects, the Apache Foundation, etc. (or maybe our readers ;o) )
