    Abstract
    The Preserved Context Index System (PRECIS) developed for subject indexing for the BNB is discussed as a basis for various studies relating to classification which could be made from its initial phrases, strings, entries and back-up structure. Specific possibilities include use of mehodologies such as Goffman's "indirect method", Fox's "characterization" of rules, derivation of empirical hyperbolic distributions, and lognormal distributions. The relationship of existing methods of subject analysis to each other through PRECIS is explored. Brief samples are included

    Abstract
    The efficiency of the role operators of PRECIS may be studied from two viewpoints - quantitative as well as qualitative. The frequency of appearance of different role operators in an input string may be taken as a measure of such quantitative parameters of efficiency. The scope of this paper lies in measuring the efficiency of role operators through their frequency of appearances in input strings. Most of the earlier research on PRECIS focused either on its general descriptions or its application to various subjects, media, languages, institutions, countries and to any regional/national/international information exchange network. No work has so far been reported which makes a quantitative evaluation of the system through its role operators except some general evaluative studies against different subject fields
