I have put directions on the wiki about the problem we had with the 2nd email notification. You can find them in the ILLiad Procedures under the Departmental page/2nd email notification and under Borrowing/Renewals.
The problem stemmed from renewals being requested prior to the patron picking the item up. That changes the status to “CHECKED OUT TO CUSTOMER” which accounted for why some books that were on the shelf were missed.
