The Swedish Heritage Board (or, more specifically, my friends Lars and Johan who work there), has begun putting historical photographs whose copyright has expired onto Flickr Commons. Well done! Check it out!
The Board is a lot like the Museum of National Antiquities: even though some of its projects just make me want to weep, it also has excellent world-class stuff going on. This is of course an effect of the individual people behind each project. And the, shall we say, wide-open-mindedness of their superiors.
