    Abstract
    This article deals with the meaningful processing of information in relation to two systems of Information processing: pre-coordination and post-coordination. The different approaches are discussed, with emphasis an the need for a controlled vocabulary in information retrieval. Assigned indexing, which employs a controlled vocabulary, is described in detail. Types of indexing language can be divided into two broad groups - those using pre-coordinated terms and those depending an post-coordination. They represent two different basic approaches in processing and Information retrieval. The historical development of these two approaches is described, as well as the two tools that apply to these approaches: thesauri and subject headings.

    Abstract
    With the current information environment characterized by the proliferation of digital resources, including collaboratively created and shared resources, Library of Congress Subject Headings (LCSH) is facing the challenges of effective and efficient subject-based organization and retrieval of digital resources. To explore the feasibility of utilizing LCSH in a digital environment, we might need to revisit its basic characteristics. The objectives of our study were to analyze LCSH in both syntactic and relational structures, to discover the structural characteristics of LCSH, and to identify problems and issues for the feasibility of LCSH as an effective subject access tool. This study reports and discusses issues raised by the syntactic and hierarchical structures of LCSH that present challenges to its use in a networked environment. Given the results of this study, we recommend a number of provisional future directions for the development of LCSH towards further becoming a viable system for digital and networked resources.

    Abstract
    Library of Congress Subject Headings (LCSH), a system originally designed as a tool for subject access to the Library's own collection in the late nineteenth century, has become, in the course of the last century, the main subject retrieval tool in library catalogs throughout the United States and in many other countries. It is one of the largest non-specialized controlled vocabularies in the world. As LCSH enters a new century, it faces an information environment that has undergone vast changes from what had prevailed when LCSH began, or, indeed, from its state in the early days of the online age. In order to continue its mission and to be useful in spheres outside library catalogs as well, LCSH must adapt to the multifarious environment. One possible approach is to adopt a series of scalable and flexible syntax and application rules to meet the needs of different user communities

    Abstract
    Library of Congress Subject Headings (LSCH), which celebrated its 100th birthday in 1998, is the largest cataloging and indexing language in the world for the indication of the topics and formats of books and similar publications. It consists of a controlled list of main headings, many with subdivisions, with a rich system of cross references. It is supported by the U.S. government, and undergoes systematic revision. In recent decades its managers have begun to confront challenges such as biased terminology, complicated syntax (how terms are put together to form headings), and effective displays in electronic media. Many suggestions have been made for its improvement, including moving to a fully faceted system.

    Abstract
    Die Diskussion um Vor- und Nachteile von Präkoordination oder Postkoordination wird unter den in der verbalen Sacherschließung Engagierten in Deutschland seit Jahren geführt. Mit zunehmender Verbreitung der RSWK gewinnen die Überlegungen, die sich angesichts der Ausbreitung des OPAC für das 'Zerschlagen' der Schlagwortketten aussprechen, an Bedeutung. In diesem Zusammenhang trägt eine Berücksichtigung der internationalen Debatte um Prä- und Postkoordination zur Erweiterung des nationalen Horizontes bei. Der Beitrag ist eine leicht gekürzte Übersetzung eines Referates, das die Autorin beim IFLA Satellite Meeting zum Thema 'Subject indexing in the 90's - principles and practices' im August 1993 in Lissabon gehalten hat

    Considers the future of LCSH and whether their viability can be maintained through a written standardization code. Until there is an online substitute for LC subject headings which has been tested on a large scale over a period of time, a successor to the present combination of LC's controlled vocabulary headings plus computerized techniques such as keyword searching is unlikely to emerge

    Abstract
    Partial coordination is a new method for cataloging documents for subject access. It is especially designed to enhance the precision of document searches in online environments. This article reports a preliminary evaluation of partial coordination that shows promising results compared with full-text retrieval. We also report the difficulties in empirically evaluating the effectiveness of automatic full-text retrieval in contrast to mixed methods such as partial coordination which combine human cataloging with computerized retrieval. Based on our study, we propose research in this area will substantially benefit from a common framework for failure analysis and a common data set. This will allow information retrieval researchers adapting 'library style'cataloging to large electronic document collections, as well as those developing automated or mixed methods, to directly compare their proposals for indexing and retrieval. This article concludes by suggesting guidelines for constructing such as testbed

    Abstract
    This paper looks at changes affecting LCSH over its 100-year history. Adopting a linguistic conceptualization, it frames these changes as relating to the semantics, syntax and pragmatics of the LCSH language. While its category semantics has remained stable over time, the LCSH relational semantics underwent a significant upheaval when a thesaural structure was imposed upon its traditional See and See also structure. Over time the LCSH syntax has become increasingly complex as it has moved from being largely enumerative to in large part synthetic. Until fairly recently the LCSH pragmatics consisted of only one rule, viz, the injunction to assign specific headings. This rule, always controversial, has become even more debated and interpreted with the move to the online environment

    Abstract
    The nature of a library's collections determines what kind of subject access to provide to those collections. The collections of the Cleveland Public Library serve both the recreational and research needs of a large urban population. The Cleveland Public Library uses Library of Congress Subject Headings to describe its collections. A study of subject searches entered by library patrons over the course of one week reveals several patterns among the types of subject headings used most frequently, reflecting the characteristics of the population served. Other topics discussed include subject access to fiction, juvenileliterature, and specialized collections

    Abstract
    Discusses the problems in establishing commonly accepted principles for subject retrieval between different bibliographic systems. The Working Group on Principles Underlying Subject Heading Languages was established to devise general principles for any subject retrieval system and to review existing real systems in the light of such principles and compare them in order to evaluate the extent of their coverage and their application in current practices. Provides a background and history of the Working Group. Discusses the principles underlying subject headings and their purposes and the state of the work and major findings

    Abstract
    The IFLA Section on Classification and Indexing's Working Group on Principles Underlying Subject Headings Languages has identified a set of eleven principles for subject heading languages and excerpted the texts that match each principle from the instructions for each of eleven national subject indexing systems, including excerpts from the LC's Subject Cataloging Manual: Subject Headings. This study compares the IFLA principles with other texts that express the principles underlying LCSH, especially Library of Congress Subject Headings: Principles of Structure and Policies for Application, prepared by Lois Mai Chan for the Library of Congress in 1990, Chan's later book on LCSH, and earlier documents by Haykin and Cutter. The principles are further elaborated for clarity and discussed

    Abstract
    Library of Congress Subjecl Headings retrieved as the results of a search in an online catalog are likely to be filed in straight alphabetical, word-by-word order, ignoring the semantic structures of these headings and scattering headings of a similar type. This practice makes LC headings unnecessarily difficult to use and negates much of their indexing power. Enthusiasm for filing simplicity and postcoordinate indexing are likely contributing factors to this phenomenon. Since the report Headings for Tomorrow (1992) first raised this issue, filing practices favoring postcoordination over precoordination appear to have become more widespread and more entrenched
