The command line, located at the top-center of Circulation, is where you enter circulation commands or barcode numbers for patrons and items. If you enter only a barcode, the current Circulation Mode (shown to the left of the command line) will determine what action is performed. By default, the command line assumes that text input is a circulation command first and a patron/item barcode second. You should follow commands with a space before a barcode, e.g. b 12092.
Select a Circulation Mode from the dropdown menu located to the left of the Command Line. The Circulation Mode field indicates which function will be implemented when patron/item barcodes are typed or scanned.
Frequently used modes are Bookdrop (B), Check Out (.), Hold (H), and Renewal (R).
