This is stunning. A dream destination, a small cove of heaven surrounded by books and nature. This is pretty cool, but I probably wouldn't get much reading done because my eyes would keep wandering back to the windows.
This is the Walstrom House by California-based architect, John Lautner. Even though I would not classify this as a library per se, I find the design of the bookshelves in the open area floorplan as a unique twist to a reading space.
