When cancelling an order in a basket there is no warning about item deletion. This can be a problem if the item is already in circulation. If the items attached to the order can not be removed, this is given a notification as the order has been cancelled. When you are cancelling an order you get a confirmation page with this text: "Are you sure you want to cancel this order (45) Bibliographic record will not be deleted." I'd like there to be a mention that the items of this order will be deleted.
