    Abstract
    Defines the basic functions of surrogate files in information retrieval. Exemplifies the categories enunciated in the general theory of classification developed in India. Defines the principles for structuring the concepts. Formulates set of general postulates pertaining to the structure of compound subjects. On the basis of these, outlines a procedure for structuring of subject headings. Demonstrates the application of procedure through examples
