Existing Cutter numbers. If a Cutter number for a province or state has been used in the shelflist or established in the classification schedule, use that number even if it is in conflict with the number in the provinces and states table.

New Cutter numbers. If a Cutter number for a specific province or state is being applied for the first time in a particular class, and there is no conflict with adjacent Cutter numbers, use the Cutter number in the table. If a conflict exists with adjacent Cutter numbers, continue the existing Cutter arrangement, adjusting the new Cutter to maintain the proper alignment.
