I adore this space, which is another example of a simple room that could have been anything, but has been deliberately turned into a library. The (premeditated, surely) haphazardness of the shelves balances the clean white--and fabulous gray--surroundings.
It really doesn't take much. Easily-accessible shelving, good lighting, and comfortable seating. The environment itself becomes a teacher when students of all ages are able to take a hint from the intellectual vibe and get excited to pick up what is around them.
