Take a book. Read a book. Share a book. Ever since I ran across a Little Free Library somewhere on my travels, I've been so taken with the idea that I'm planning to install one in front of our house in Boston, where we get plenty of foot traffic. The concept is simple: books are free to anyone. Some people will take, some will leave their own books in the library. I love the variety of designs (the one above is eco-friendly, with a solar panel in the chimney that powers a light inside at night); follow the official Little Free Library Pinterest board to see more.
