Little Free Library is a grassroots initiative to build more libraries around the world than philanthropist Andrew Carnegie did (he built 2,510). The libraries in question are tiny dollhouse sized structures that serve as free community book exchanges. To date more than 200 have been installed in more than 20 countries. Little Free Library was founded by Todd Bol and Rick Brooks, both of Wisconsin.
