Lu, John Markham, David Cybernetics Information Processing Information Retrieval Information Storage Information Systems Information Theory Information Utilization Research Utilization Search Strategies This paper demonstrates an approach which enables one to reduce in a systematic way the immense complexity of a large body of knowledge. This approach provides considerable insight into what is known and unknown in a given academic field by systematically and pragmatically ordering the information. As a case study, the authors selected approximately 1200 titles from the Engineering Branch Library at the University of California at Berkeley whose face validity suggested application to the interests of cybernetic systems personnel. They developed a hierarchic methodology (a structure consisting of four levels--theoretical systems, mechanics, control, and information--in which the first level is the most basic echelon and the remaining three are encompassed by the ideas found in the first level) to promote inductive investigation and retrieval from this aggregate of varied titles. The authors discuss the results of their experiment using this structure and the implications for solving complex problems involving large bodies of knowledge through use of this hierarchic methodology.
