Only the account administrator can remove books from My Bookshelf. If you are not sure if you are logged in as the Account Administrator, please log off and then log back in again using your account administrator login.
After a book has been added it will stay on the My Bookshelf for 30 days. On or after the 30-day mark a book can be removed from My Bookshelf. Once a book has been removed from My Bookshelf, those slots are free for you to add new books. Click on the My Bookshelf tab to see when books are eligible for swapping. To remove a book, click on the Remove tab.
