• BC2 classes for phenomena : an application of the theory of integrative levels

      Gnoli, Claudio; Curwen, Tony (Bliss classification association, 2005-09)
      Discusses classes 4/6, for phenomena treated in a multi-disciplinary way, in the Bliss Classification 2nd edition, and relates them with the studies on application of the theory of integrative levels by the Classification Research Group. Suggests that disciplines and phenomena can coexist in an "accordion-like" classification scheme.
