Klaus Graf has written an update for authors of research literature published in Germany before 1995. There is a beautiful opportunity to make those works OA, but it requires action before the end of this month. Read Klaus' update in the original German or Google's English.
PS: For some background in English, see my post from late November.

Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
