Its idea is simple: instead of leaving books unread on shelves or in storage, members can make them available to other local readers, giving each book a new life and a wider audience. In return, members can discover and borrow books shared by others in their neighborhood.

The service is free and designed to make borrowing convenient, local, and social. As more people list their books, the shared collection grows into a distributed neighborhood library, connecting readers across a building, street, or wider community. biblioShare encourages members to spread the word, participate in lending, and build relationships through shared reading experiences. The website offers ways to join, search for books, lend them, and learn how the service works, alongside frequently asked questions, a manifesto, and a blog. Its central aim is to make better use of books already in circulation while making reading resources accessible close to home.
