    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.

    Abstract
    This fourth paper in the series on PRECIS will consider the theoretical model of the indexing operation proposed in an earlier paper, and extend its application to one of the Romance languages, namely French. The present author has noted, throughout the publication of this series, how closely these logico-linguistic explanations could be applied to indexing in the French language. It is realised that experiments into PRECIS as a multilingual system are not complete, and that a new phase has undoubtedly started with the current British Library investigation of its translingual potential. Nevertheless, it would appear that the major problems still facing the researchers, such as the treatment of inflections, infixes, etc., are mostly related to the Germanic languages. As far as French is concerned, it is a relatively simple matter to give a positive answer to the question posed in the first paper: " . . . Do the codes and procedures developed so far (including the specified additions) amount to a general system which is capable of operating in any of the major European (and other) languages?"

    Abstract
    89 articles from a small, Danish left-wing newspaper were indexed by PRECIS and KWIC. The articles cover a wide range of social science subjects. Controlled test searches in both indexes were carried out by 20 students of library science. The results obtained from this small-scale retrieval test were evaluated by a chi-square test. The PRECIS index led to more correct answers and fewer wrong answers than the KWIC index, i.e. it had both better recall and greater precision. Furthermore, the students were more confident in their judgement of the relevance of retrieved articles in the PRECIS index than in the KWIC index; and they generally favoured the PRECIS index in the subjective judgement they were asked to make

    Abstract
    The first opportunity to assess a largescale application of the PRECIS indexing system in North America came with its adoption by the National Film Board of Canada as the method of subject access to a national information system for Canadian audiovisual materials. The authors provide an overview of PRECIS use by this automated bibliographic service - the reasons for its choice, the challenge involved in the subject analysis and indexing of audiovisual documents, the methodology and software used to process PRECIS records, the resulting catalogue subject indexes and user reaction
