    Abstract
    We developed a project utilizing the local form/genre heading, "property data," and specific subheadings to help chemists, engineers, and those librarians assisting them to more easily locate library resources containing chemical and physical properties of substances. This article describes the project and examines possibilities for improving access to physical sciences literature in relation to Library of Congress Subject Headings and ongoing developments in authority records for form/genre terms. It also introduces functionality of such headings in the new "next generation" catalogs.

    Abstract
    The criticisms made against chain indexing are reviewed, and PRECIS briefly considered as a possible (but improbable) general substitute for indexing. The failures of chain indexing arise mainly from an inherited overemphasis on generic relationships, encouraged by careless use of the term 'chain'. The use of symbols to represent relations between terms is suggested for the chain index, to emphasize syntagmatic relations and prevent ambiguity. These relationships can be used to manipulate the index terms into likely additional index approaches, employing the logical concepts of symmetry and transitivity which derive from a structure inherent between relations, a sort of 'metarelations'. The transitivityy of the relations of action or property to object over the relation of material to object are particularly considered, and clues to this relational structure obtained from Aristotle's theory of causation

    Abstract
    Probably the most interesting, original and controversial indexing system of the 1970s has been PRECIS (the Preserved Context Index System) developed by Derek Austin. It attracted such attention that the short courses given at the British National Bibliography offices in London -initiated as a means of teaching the staff of BNB who did subject indexing-were repeated all over the world, in the form of three-day or three-week sessions. A few fortunate non-BNB indexers were taken into London classes, taught by Austin and Digger, and had the advantage of a week's work with the regular staff theresomething that could not be done elsewhere. In addition, descriptions of the system were published from time to time as progress was made an the system itself and clarification or updating were needed. This article has been selected as an example of clarification. A second edition of the original 1974 Manual describing PRECIS appeared in early 1984, so the system may now be regarded as fully mature. PRECIS, which is the culmination of Austin's research for the Classification Research Group plus considerable additional input from the science of linguistics, is a highly sophisticated indexing system, deliberately created to be used with a computer. The motive behind it was that the indexer should do the brain work and the computer the nitty-gritty work of manipulating index terms. Chosen combinations and permutations are used as head words under strict rules to ensure that the context which defines the specific meaning of these words is always present, thus avoiding the ambiguity problem in indexing. The system also has classifi ation features, in part drawn from the Group's long interest in faceted classification. The actual index produces a large number of index entries, each carrying with it the basic context of the item being described. A weIl-defined terminology, in addition to contextdependency, is a feature of PRECIS. Role operators define the types of terms used and control the manipulations of the terms, which are originally entered as a string. The indexer is able to analyze and reduce to string form any document, process, or material that can be described in words, making it ideal for most audiovisual material.
    The system itself has two major aspects: - a syntactic approach in which relationships between terms are identified and tagged. Suitable algorithms for manipulation produce a very thorough index in which each head word is kept in context. - a semantic approach in which terminology is weIl defined by ensuring that the relationships of equivalence, hierarchy, and association are clearly established. Charts of relationships are created by inductive means (i.e., from the ground up). A special code for computer manipulation is used with each line of the string. This translates the string format into one that, with specially derived algorithms, can be used by the computer, to produce the actual index headings with all parts rotated by following the algorithm. The PRECIS system has been translated and utilized for languages other than English, notably French, German, and Danish. Modifications needed for idiosyncracies of each language have been made. Some, such as those modifications needed for German, have turned out to have usefulness with English as weIl. All in all, the system has such advanced indexing concepts that it provides a kind of indexing not possible before the computer came into common usage. Austin, who joined the staff of the British National Bibliography in 1963, is currently a member of the British Library staff. His early work included a NATO-sponsored research assignment for the Classification Research Group (q.v.). This, in turn, led to the development of PRECIS.

    Abstract
    Over the last ten years, the Servizio Bibliotecario Nazionale (SBN) has become the largest Italian network of bibliographic services. The creation of the SBN Index database and its growth through shared cataloging were the focus of attention during the early phase, and for years, discussion was limited to questions of author cataloging and bibliographic description. Subject cataloging was excluded from the cooperative activity of the member libraries. In 1990 the Working Group on Subject Headings and Classes was established to examine this situation. First, a partial solution was found, to permit the launch of the network itself. This was followed, several years later, by the development of the SBN OPAC and the creation of the file of subject headings and classes in the SBN Index. From an operational perspective, the choice was made to forego managing the subject headings file in accordance with shared cataloging principles, with mixed results. In order for the subject file to have broader coverage and to further encourage cooperative subject cataloging, the SBN Index Development Program, in which the Istituto Centrale per il Catalogo Unico delle Biblioteche Italiane (ICCU) has been engaged for about two years, aims at enriching services of the database and opening up new and diversified types of usage. Almost simultaneously the Biblioteca Nazionale Centrale di Firenze (BNCF) initiated a feasibility study on the revision of the Soggettario delle biblioteche italiane (List of Subject Headings in Italian Libraries) for the catalogs of Italian libraries. Both the BNCF and the ICCU share the goal of building a new, consistent vocabulary for documentation of subject matter.

    Abstract
    In the preparation of a book on how to do a literature search, many inconsistencies were found in the assignment of subject terms. The Library of Congress Subject Headings is cited for not bringing computer languages into a consistent pattern. BASIC and FORTRAN are treated differently in their see also references and are without references to the words "computers" or "computer." Also index terms for the literature search on the "search for extraterrestrial life" showed inconsistent patterns in indexing. Catalogers and indexers need to review the work they are currently publishing and try to decide how to bring some standardization to the construction of subject terms. There is a need to provide a single thesaurus for all English index terms.

    Abstract
    The Nuovo Soggettario is a subject indexing system edited by the Biblioteca Nazionale Centrale di Firenze. It was presented to librarians from across Italy on 8 February 2007 in Florence as a new edition of the Soggettario (1956), and it has become the official Italian subject indexing tool. This system is made up of two individual and interactive components: the general thesaurus, accessible on the web since 2007 and the rules of a conventional syntax for the construction of subject strings. The Nuovo soggettario thesaurus has grown significantly in terms of terminology and connections with other knowledge organization tools (e.g., encyclopedias, dictionaries, resources of archives and museums, and other information data sets), offering the users the possibility to browse through documents, books, objects, photographs, etc. The conversion of the Nuovo soggettario thesaurus into formats suitable for the semantic web and linked data world improves its function as an interlinking hub for direct searching and for organizing content by different professional communities. Thanks to structured data and the SKOS format, the Nuovo soggettario thesaurus is published on the Data Hub platform, thus giving broad visibility to the BNCF and its precious patrimony.

    Abstract
    The Deep Structure Indexing System is based on: (1) a set of postulated elementary categories of the elements fit to form componentes of names of subjects; (2) a set of syntax rules with reference to the categories; (3) a vocabulary control tool such as Classaurus; (4) a set of indicator digits to denote the categories and their subdivisions; and (5) a set of codes to denote a few of the decisions of the indexer. Names of subjects formulated on the basis mentioned above are input to a set of computer programs to generate several different types of subject index entires. This paper describes briefly the Deep Structure Index System

    Abstract
    Many kinds of structure can be discerned in the headings and rules governing the Library of Congress Subject Headings. By addressing these structures at different levels, librarians can develop different approaches to the machine-assisted validation of subject headings, from the checking of individual words to the validation of complex forms of heading/subdivision compatibility. Using computer programs to assist with maintenance of subject headings is becoming increasingly necessary as technical services librarians strive to create consistent and useful patterns of subject collocation in library catalogs

    Abstract
    This paper presents a study that assessed the feasibility of applying the approach of the Faceted Application of Subject Terminology (FAST), an initiative of the Online Computer Library Center (OCLC), to records in the Ulrich's Periodicals Directory.? The goal is to determine whether a simplified application of Library of Congress Subject Headings (LCSH), as illustrated by FAST, would benefit the Ulrich's system. This feasibility study found that although a few problems were encountered in the process, overall the FAST database was useful for converting Ulrich's subject headings into FAST headings.

    Abstract
    The introduction of computerized post-coordination has solved many of the problems of pre-coordinated subject access. However, the adoption of computerized post-coordination results in the loss of some pre-coordination benefits. Specifically, the effect of hiding terms within the context of others is lost in post-coodination which give lead status to every document term. This results in spurious matches of terms out of context. Library patrons and Internet searchers are increasingly dissatisfied with subject access performance, in part because of unmanageably large retrieval sets. The need to enhance precision and limit the size of retrieval sets motivates this work which proposes partial coordination, an approach which incorporates the advantages of computer search with the ability of pre-coordination to limit spurious partial matches and thereby enhance precision

    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.
