In 2009, Todd Bol built the first Little Free Library as a memorial to his mom. Five years later, this simple idea to promote literacy and encourage community has become a movement. Little Free Libraries--freestanding front-yard book exchanges--now number twenty-five thousand in seventy countries. The Little Free Library Book tells the history of these charming libraries, gathers quirky and poignant firsthand stories from owners, provides a resource guide for how to best use your Little Free Library, and features color images of the most creative and inspired LFLs around.
