Somehow I have missed seeing this until now. I don't quite know why as it seems to have been all over the internet for ages and it is AWESOME and BEAUTIFUL and AWESOME again. And totally the kind of thing I love. A massive library full of books.
So, it is totally worth showing and sharing, but due to the been-all-over-the-internet-for-years part, no article, just pictures. (If you do want an article there are lots, but I did like this one).
