This is the first one I found, and it's still one of my favorites.
I always enjoyed ones that had quotes or slogans about reading.
Two even provided a nice place to sit.
I think this little phone booth came from the website.
This last one was made by the owner from thrift store materials. When I was taking my picture she came out and we talked about it. It was hard to photograph with so much glass, but it really is lovely.
Everyone who I spoke with about the Little Free Libraries loved them. They seem to provide a neighborhood with a sense of community. I read quite a lot of books, and usually give them away after I'm done. Maybe it's time I build my own Little Free Library.
