Add, remove or move books from the group shelf
You can add, remove or move books on your group's shelf by clicking on the book cover and going to the book page. Click the "Add/Remove from my group" link in the upper right hand of the book page. This link takes you to a page where you can manage which group shelf this book is added to, move the book between We're Reading and We've Read, or remove the book from a group shelf.
