Not all libraries are in big buildings. Some libraries are very small. In fact, a LITTLE FREE LIBRARY can be the size of a birdhouse. Some are even built inside the trunks of old trees.
A Little Free Library is a book exchange. Anyone can start one. Most of them are wooden boxes filled with books. Neighbors can take a book. Then they are allowed to leave one for someone else. “It’s a great way to share a love of reading and share a feeling of community,” Margret Aldrich of Little Free Library told TIME for Kids.
