Reading books is an important part of a child’s life. And it’s also a great relaxation hobby for adults. In an effort to share books with the public, Little Free Library was founded in 2009. The nonprofit organization promotes neighborhood book exchanges.

But this is no ordinary book exchange. Books are exchanged through more than 90,000 public book boxes around the world. The organization’s mission is to “inspire a love of reading, build community, and spark creativity by fostering neighborhood book exchanges around the world.”

These “tiny libraries” are located in front of homes, in city parks, in public schools, and in other fully accessible areas. The idea is simple: Anyone passing by a book box can take a book that’s inside or leave one if they want to. The boxes are either pre-built or custom made. Anyone can “host” a little free library.

We found 60 photos of adorable free libraries people have built for their neighborhoods. Check these out!
