Four-figure cutter tables

The resolution power of the cutter tables has diminished due to growth in library collections and the increasing incidence of corporate name and title main entries. Heavily used cutter numbers routinely require adjustment to prevent shelflist conflicts and to establish unique call numbers. OCLC's expanded cutter tables balance the distribution of main entries over the cutter table entries and eliminate some of the manual processing required to complete call numbers in Dewey classes with extensive holdings. The expanded cutter tables are compatible with existing two-figure or three-figure schemes, but also include new features that enhance their versatility and facilitate algorithmic cuttering.
