Here in my hometown of Birmingham, Alabama, we have some charming little "book houses' on posts stationed around town. I love this free library concept. You share your gently read books and take another from a generous neighbor.
Last November during our walk from the center of Rueil-Malaison to the chateau, we came upon the French version. These former phone booths are now transformed into a lovely free library. Now I'm regretting I didn't do a little shopping!
