If an item is reserved, Harry will politely say that it may not be renewed. Items can only be renewed one time. Each day a list of patrons with overdues and items being held is generated. Harry calls the patrons on that list. Before he delivers a message, he asks for verification that the person on the line is the person for whom the message is intended.
Verification is by barcode number.
If the person indicates that patron is not available, Harry hangs up and calls another time. When there is no response, Harry assumes an answering machine has answered and delivers his message. He repeats the message 3 times to make certain it is properly recorded. When the patron is told he has an overdue item, he is given the option to renew that item and to hear his current fines. If an item is being held, the patron may confirm that hold or cancel that hold.
