LA CROSSE, Wis. (WEAU) - There is a new addition to the La Crosse area Children's Museum.

People who head to the museum with will now come across the "little free library".

The 'take a book, leave a book' library was built and painted by local families.

Organizers say the little free library books are always a gift, and never for sale.

They say the idea started in Madison in 2010. Since then, there are "little free libraries" in most states, and in dozens of countries.
