Segmentation is often indicated in DDC numbers by using apostrophes to show where a meaningful number can be ended. For example, 025.4’31 means that 025.431 is the complete number, but 025.4 is also correct (although less specific).']][^5] --- ### Universal Decimal Classification (UDC) [[2023-0917.
