“Not only was I not a librarian, I wasn’t even really dealing in reading material. That the objects in our Little Free Library happened to be books was beside the point. The salient fact was that the items were free. We may as well, I suspected, have been offering plastic spoons, Allen wrenches and facial tissue. I tested this hypothesis by mixing in non-book items including an instructional DVD on how to use an exercise ball, and a few packets of echinacea seeds.”
