    Abstract
    Derek Austin's PRECIS, or PREserved Context Index System, was one of the most sophisticated indexing systems ever developed for text. Austin noted that there are many ways that the meaning of index entries may be misread and misunderstood, if the original context from which the concept came was not present. Drawing on a good understanding of linguistics, Austin and his colleagues developed a highly rigorous, yet not impossibly difficult, set of principles to use in indexing with the help of PRECIS. The system was particularly valuable for generating multiple word orderings of entries that still retained their proper contextual meaning. Much of the need for this feature was obviated by the development of powerful full text searching in information systems, however, and PRECIS receded from view in information science. The final sections of the article that address the details of coding and indexing management are deleted from the text below.

    Abstract
    Designing research on the retrieval effectiveness of computer searches on PRECIS compared with retrieval effectiveness of searches on other types of subject analysis used in computer-based information sources is a complex process. This paper explores the complexity of measuring comparative retrieval effectiveness through a comparison of the subject analysis provided by the PRECIS system for fifty articles with the subject analysis provided for the same articles by three computer-based information sources: ERIC/CIJE, LLBA/Online and PsycINFO. Objectives are: (1) to discover factors that should be taken into account when designing this type of research; and (2) to identify extraneous variables that work against internal validity in research design .

    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

    Abstract
    One current trend in information retrieval that can facilitate resource sharing and cost reduction is the sread of common indexing languages. Of the more sophisticated languages available, clearly the best known and widely adopted is PRECIS. One of the claims made for PRECIS by its designer is that the role operators it uses correspond to linguistic universals, making PRECIS eminently suitable for multilingual indexing. This strong claim, if justified, could make PRECIS the common indexing language of choice where translation problems have high priority, as they do in Canada. This paper shows there is little support for this claim to universality because the role operators are defined in terms of superficial characteristics of language that are far from universal

    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
