    Abstract
    The terms which comprise an entry in an index can be arranged in various ways. The use use roles or facets such as 'thing-action-part-effect' under which terms can be categorized allows the use of citation orders which preserve the syntactic relationships between terms in a string. Alphabetization and rotation in context are simple methods but with certain disadvantages for the users. The citation order of BTI results in a detailed index using punctation to indicate relationships. PRECIS incorporates prepositions which preserve necessary entries. Articulated indexes use natural language phrases displayed under selectes subject headings. These methods could be used to construct book indexes

    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 present paper is offered as the first of a series of articles in which PRECIS will be reviewed as a potential multi-lingual system, having in mind the obvious need, notably in a European context, for standard and language independent methods of subject analysis and document description. This first paper outlines the origins of PRECIS, and considers its use in English language indexing. A second paper will deal in general terms with the syntactical model which is used for producing PRECIS input strings and index entries. Later papers will then review the application of this model to indexing in, firstly, the Germanic languages (e.g. German and Danish), and, secondly, the Romance languages, illustrated by French.
