Just found this site and it appeals greatly to my idea of ownly owning what I need to own and only to keep objects that have sentimental value or extended use. Most books do not fall into this category for me as once read they can be passed on. This seems like a fun way of achieving that, reducing my impact on the planet and allowing someone else to have the enjoyment of the books that would otherwise languish unused on a shelf or even worse in a box at the back of a cupboard. Release them all into the wild I say.
