"Take a book. Return a book." That is the catch phrase of Little Free Library.
Started in 2009 in Wisconsin, the brilliant idea of placing a small structure to house books in someone's front yard, with access to a variety of books at all times of day and night, is thanks to Todd Bol.
The first Little Free Library looked like a miniature red schoolhouse. All Little Free Libraries have the unique style of their stewards, but all provide a place safe from the elements for books. Little Free Libraries have spread all over the world, with the number of registered building over 25,000. To learn more about Little Free Library, go to their website.
