New libraries are popping up all over Colorado. They are tiny libraries about the size of a birdhouse. The idea of little free libraries started with two book lovers in Wisconsin who had a mission. They wanted to break Andrew Carnegie's record of creating more than 2,500 new libraries. They have surpassed their goal. There are now thousands of libraries all over the world, including about 50 in Colorado. Ryan Warner talks to Kari Armstrong about the little library she brought to Boulder.
