A private shelf for your circle. Lend and borrow the physical books you already own with friends — and never lose track of who has what.
Your library is private by default — only the people you connect with can see your books.
Shelf is for the paper books on your shelves — not e-books. Lend a copy to a friend and get it back when they're done.
Shelf tracks due dates and sends automatic reminders — so you never have to awkwardly ask for your book back.
