“The CRG turned its thoughts towards a much more complex matter that had received little attention from any of the other schools of thought which had been represented at the two Conferences [Dorking and ICSI]. This is the relation between general and special classifications: is there anything to be gained by pursuing the ideal of a new universal classification scheme, and if so, how will the specialist's need be served by it? How can the CRG schemes, for example, that prove so satisfactory for their users, be integrated into such a general scheme?”
