Librophiliac Love Letter: A Compendium of Beautiful Libraries
Don't be intimidated by the title. It's basically a collection of images of the most beautiful libraries in the world. Just gorgeous.
My favorite - about one-third of the way down the page: Handelingenkamer Tweede Kamer Der Staten-Generaal Den Haag, the Hague, Netherlands Surprise, surprise. It's a gorgeous red color. And that spiral staircase? Gorgeous.
