    Abstract
    PRECIS ist ein Indexierungssystem, das ursprünglich zur Herstellung des Sachregisters für die 1971 auf maschinelle Verarbeitung umgestellte BNB entwickelt wurde. Obwohl für das Englische entworfen, hat sich PRECIS bisher in einer Reihe anderer Sprachen bewährt. Die British Library finanziert seit 1976 ein Projekt, dessen Aufgabe es ist, das Potential von PRECIS als zwischensprachliche Indexsprache zu ermitteln. Es wird vor allem mit Deutsch, Französisch und Englisch gearbeitet. Das Forschungsteam hat eine Anzahl Mechanismen entwickelt, die verbale Indexierungsdaten in Form von "Eingabeketten" von einer Ausgangssprache in eine Zielsprache maschinell umsetzen. Jeder Begriff wird dabei einzeln umgesetzt. Diese Begriffe, die ein Sachverhaltspaket bilden, werden dann von einem Standardprogramm gelesen, das auch Registereinträge in einer Zielsprache oder Zielsprachen erstellt

    Abstract
    Dieser Aufsatz beschäftigt sich mit Management-Aspekten der Sacherschließung in der British Library, Bibliographic Services Division, wo computergestützte, nicht völlig "automatische" Verfahren angewendet werden. In einer ausführlichen Darstellung des Arbeitsablaufes im Subject Systems Office wird der Weg eines Dokumentes durch die verschiedenen Sektionen verfolgt, und die betriebswirtschaftlichen Folgen der besonderen Rolle von PRECIS in diesem Arbeitsablauf werden erörtert. Das Mehrdateiensystem der British-Library-Datenbank wird beschrieben; es wird gezeigt, wie diese Struktur den effektiven Wiedergebrauch von Daten ermöglicht. Weiterhin wird die Verbesserung des on-line Retrieval durch den Einbau von präkoordinierten Themenangaben in den Suchablauf behandelt; abschließend wird die Rolle des Computers in der Sacherschließung einer IuD-Einrichtung wie der British Library diskutiert

    Abstract
    Kurze Beschreibung des verbalen Indexierungssystems PRECIS, seiner Ursprünge und Entwicklung, seiner Bestandteile und seiner Ziele. Im einzelnen wird an Beispielen gezeigt, wie das Format einer PRECIS-Eintragung aussieht und wie die "Mechanik" der Eintragungsgenerierung mit Computerhilfe abläuft, wobei auch auf die Rollenoperatoren eingegangen wird. Abschließend eine Darstellung der Anwendung von PRECIS in anderen Sprachen, hier in Deutsch. An der Produktion von Eintragungen zum Austausch zwischen den 4 Sprachen Englisch, Französisch, Deutsch und Polnisch wird gegenwärtig gearbeitet. Untersuchungen für die skandinavischen Sprachen sind geplant

    Abstract
    Die deutsche Bibliothek in Frankfurt bietet seit einigen Jahren zentrale Dienste im Bereich der verbalen Sacherschließung an, Um deren Akzeptanz zu verbessern, will die Deutsche Bibliothek ab 1986 von der augenblicklichen gleichordnenden Indexierung zu einem syntaktischen Verfahren übergehen. Als Alternativen standen die RSWK und eine verkürzte Version des britischen Indexierungsverfahrens PRECIS zur Diskussion. Die Anforderungen einer Fachwissenschaft an die Schlagwort-Syntax einer adäquaten Dokumentationssprache werden exemplarisch entwickelt, die vier Alternativen - augenblickliche verbale Sacherschließunf der DB, RSWK, PRECIS (britische Version) und Kurz-PRECIS (DB-Version) - an ihnen gemessen. Die Kriterien basiern auf Grammatiktheorien der modernen Linguistik und gehen von einer Analogie zwischen Dokumentationssprachen und natürlicher Sprache aus.

    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
