Building on the arguments of earlier papers, this paper advocates the
use of centro-symmetric diagrams, controlled through suitable graphics
software, to hold and re-configure concept sets - whether user initia
ted or supported by a library of such sets. It is emphasized that comp
uter software features have evolved to such a high degree that it is w
orthwhile challenging any new approach to knowledge organization with
the question: ''what could that software feature offer to knowledge or
ganization?''. Often the software already available offers facilities
superior to the needs articulated or envisaged by those concerned with
knowledge organization.
