Have you seen the new Little Free Library at the Bethlehem Center in Alton Park?
Little Free Library is a nonprofit dedicated to increasing book access for all through a network of volunteer-led micro-libraries, usually in the form of a public weatherproof bookshelf built by an individual or group. People can come and get a book for free, so long as they leave a book in return. Currently there are 49 registered Little Free Library book-sharing boxes across Chattanooga -- and probably more since not all of them are registered.
The cost to register one is $60, and anyone can do it. Likewise, anyone can build and install one -- though, if you'd rather not build one from scratch, pre-built libraries are available on Little Free Library's website, with options beginning around $170 and all purchases helping support the nonprofit's mission to inspire readers.
