The Library of Congress has a Flickr account. And they've been posting the most kickass photography I've ever seen. Several thousand in each of two sets (what, nobody's bought them a Pro Account?). They're beautiful photos. It seems like they were taken with slide film--I'm not sure how else they'd get focus that sharp with such insanely sharp contrast and beautiful color.
What's more, those titles, they are (ah!) lovely.
Very writerly in their descriptions. Except maybe the girl in the glass bubble. But that's too great a picture to pass up.
