I came across this article from UTNE Reader:
It's about a couple of fellows in Wisconsin who are building little tiny birdhouse sized libraries that offer free books to the community. Ideally, in a perfect world patrons leave a contribution when they take a book or return books that they've borrowed, but there's no requirement to do so. There's no library card, no due date - just book karma and enjoyment. I LOVE the concept and would love to see something like this come to my community - it might inspire folks to pick-up a book they wouldn't otherwise discover in the stacks of their regular public library or browsing on Amazon and we all know there's NOTHING like finding an unexpected fantastic novel (or audiobook). Kudos to Rick Brooks and Todd Bol! Anyone want to sponsor one in Vermont?
