Zero Rights: Creative Commons License - Linux Magazine Online: "Various definitions exist for the term 'public domain' throughout the world. In the U.S., for example, the general rule is that pre-1923 published works are public domain, unpublished works are under federal copyright for at least the life of the author plus 70 years. In Germany and Austria, the 'Gemeinfreiheit' term generally applies to the lifting of copyright from works (artwork and text) 70 years after the death of the author. Public domain and its equivalent German term are, however, subtly different concepts, as is the case in other international contexts."
