A book box allows you to share books that you enjoyed.
The box can be indoors or outdoors (which requires a suitable material like an outdoor wood). For outside boxes, maintenance every 2/3 years may be required.
An agreement with the local library may allow new books to be added to the box.
A poster on the side can explain the operation. We take a book and we can bring it back or bring another one that we want to share.
