The operator locates the correct trays, retrieves the item and either records the barcode information at this point or takes the book to the staff work area. The item barcode number is scanned as it is removed from the tray. The operator charges out the item to either the user or to a library on campus for them to circulate to the user. A shipping slip is sent with the item. Replacing items and trays on shelves Bins from libraries arrive at regular intervals at the warehouse.
Items arrive at the warehouse.
The item barcode is scanned to discharge the book from the person or library returning it. The system checks the list of available trays and spaces within trays of the correct size, knows where the item was last shelved and makes a recommendation for reshelving in the correct size tray. A return list is generated for the mechanical list operator on the basis of this information. Using the return list, the operator locates the appropriate tray, and adds the returned item to it. The tray barcode and the item barcode should be scanned at this point for verification of location.
