HUDSON, Wis. (AP) — It started as a simple tribute to his mother, a teacher and bibliophile. Todd Bol put up a miniature version of a one-room schoolhouse on a post outside his home in this western Wisconsin city, filled it with books and invited his neighbors to borrow them.

They loved it, and began dropping by so often that his lawn became a gathering spot. Then a friend in Madison put out some similar boxes and got the same reaction. More home-crafted libraries began popping up around Wisconsin’s capital.
