They look like large birdhouses and act like water coolers. But the sustenance stored inside the wooden, windowed boxes is a blend of knowledge and recreation.
Little Free Libraries, the brainchild of Stillwater native Todd Bol, are popping up all over Minnesota, from tony Lowry Hill to St. Paul's rough-and-tumble East Side to placid Detroit Lakes.
Usually planted near streets and seeded with their owners' books, the libraries can hold about two dozen volumes. Working on an honor system -- a sign on the side reads "Take a Book, Leave a Book" -- the boxes tend to stay stocked with contributions from those who happen upon them and find a book or three to take home.
"It's always moving -- paperback, hardcover, kids' books. We are not having to feed much," Mary Kloehn of Minneapolis said. "We're reading a great book now that somebody put there. It's like a dynamic library in our front yard.
"We live in a neighborhood where you can spit on the next residence, but that still doesn't mean you talk to them. These people across the street stopped and talked to us for the first time ever by the library."
That's a common occurrence, according to Bol, who now lives in Hudson, Wis. He came up with the idea two years ago and started the nonprofit company Little Free Library with his friend Rick Brooks of Madison, Wis.
"What we have found is that the neighborhood starts to feel like it's theirs," Bol said. "The neighborhood starts taking care of it. People come together to talk about literacy, education -- community things that we define so well but lack so much. There is such polarity these days that this is a little common place that we're comfortable with."
Bol has enlisted several other builders, including an Amish man who uses wood from 100-year-old barns and Forest Lake residents who work with recycled sawdust. Recycling has been a theme all along: Some of Bol's first libraries came from a barn that blew down when a tornado hit Ogema, Wis.
