From a distance, they seem like cute mailboxes. But take a closer look, and you’ll find that these colorful streetside boxes, perched on wooden poles, offer much richer reading material. Each Little Free Library houses a diverse array of free books that are ripe for the taking 24/7, so readers of all ages and backgrounds can find a book that they personally connect with.

The global organization behind these literary treasure troves just passed a major milestone: unveiling its 200,000th box. Little Free Library cut the ribbon on the brand new box at Benjamin E. Mays IB World School in St. Paul, Minnesota today — and it brought out students, school staff, and other community members to join in with snacks and, naturally, dedicated reading time.
