Perhaps you've seen the posts on various blogs about the world's most modern library. (the DOK in Delft, Holland) If not, take a gander at the shifted librarian. Sweet, huh?
But hey, if a hip-happening library is what you're after, then go no further than my backyard - that is, an hour away in Charlotte.
Imaginon calls itself A Library For Youth, A Professional Children's Theater, and so much more. Follow the link and see if you don't agree about so much more....
I only wish I had so many more and better pics to showcase the delightful environs.
