    Abstract
    In this article, we describe and test a two-stage algorithm based on a lexical collocation technique which maps from the lexical clues contained in a document representation into a controlled vocabulary list of subject headings. Using a collection of 4.626 INSPEC documents, we create a 'dictionary' of associations between the lexical items contained in the titles, authors, and abstracts, and controlled vocabulary subject headings assigned to those records by human indexers using a likelihood ratio statistic as the measure of association. In the deployment stage, we use the dictiony to predict which of the controlled vocabulary subject headings best describe new documents when they are presented to the system. Our evaluation of this algorithm, in which we compare the automatically assigned subject headings to the subject headings assigned to the test documents by human catalogers, shows that we can obtain results comparable to, and consistent with, human cataloging. In effect we have cast this as a classic partial match information retrieval problem. We consider the problem to be one of 'retrieving' (or assigning) the most probably 'relevant' (or correct) controlled vocabulary subject headings to a document based on the clues contained in that document

    Abstract
    Currently, few resources exist to guide libraries in the cataloguing of community information using the new USMARC Format for Cammunity Information (1993). In developing a community information database, Queens Borough Public Library, New York City, formulated their own cataloguing procedures for applying AACR2, LoC File Interpretations, and USMARC Format for Community Information to community information. Their practices include entering corporate names directly whenever possible and assigning LC subject headings for classes of persons and topics, adding neighbourhood level geographic subdivisions. The guidelines were specially designed to aid non cataloguers in cataloguing community information and have enabled library to maintain consistency in handling corporate names and in assigning subject headings, while creating database that is highly accessible to library staff and users

    Abstract
    Reports results of a bibliometric study of the literature of Qigong: a relaxation technique used to teach patients to control their heart rate, blood pressure, temperature and other involuntary functions through controlles breathing. All articles indexed in the MEDLINE CD-ROM database, between 1965 and 1995 were identified using 'breathing exercises' MeSH term. The articles were analyzed for geographical and language distribution and a ranking exercise enabled a core list of periodicals to be identified. In addition, the study shed light on the changing frequency of the MeSH terms and evaluated the research areas by measuring the information from these respective MeSH headings

    Abstract
    Although the rules for descriptive cataloging have been recodified twice in the past twenty years, there never has been any kind of comprehensive theoretical code for subject headings, despite some suggestions for a code over the years. This essay explains the need for a code, provides historical background, and presents some broad proposals as to the philosophy, structure, and form of the code and what the code should cover. Included is the relation between the proposed code and the Library of Congress' 1984 Subject Cataloging Manual.

    Abstract
    The paper examines whether subject headings in a bibliographic description could be used to direct users to relevant archival sources: a publication about a subject is likely to cite archival sources that are related to the subject. In the light of the data collected for the paper this approach might work in case of some keywords. However, there are also problems, like finding the optimal level the user should be directed to in the archival hierarchy, and the lack of information in archival persistent identifiers (PIDs).

    Abstract
    This research concerns the frequency of the assignment of author-supplied keyword strings and cataloger supplied subject heading strings within a library catalog. The results reveal that, on average, more author-assigned keywords and more cataloger-assigned Library of Congress Subject Headings were assigned to works emerging from the arts & humanities than to works emerging from the social sciences and science, technology, engineering, and mathematics (STEM) disciplines. STEM disciplines in particular received a lower amount of topical metadata, in part because of the under-assignment of name/title, geographical, and corporate subject headings. These findings reveal how librarians could increase their understanding of how topical access is functioning within academic disciplines.

    Abstract
    A study group representing four European national libraries (the Swiss National Library, Die Deutsche Bibliothek, the Bibliothèque nationale de France and The British Library) recently conducted a study on the possibility of establishing multilingual thesaural links between the headings in the LCSH authority file and the authority files of the German indexing system SWD/RSWK and the French indexing system RAMEAU. The study demonstrated a high level of correspondence in main headings, but also revealed a number of issues requiring further investigation. The study group's findings led to recommendations on the scope for the development of a prototype system for linking the three Subject Heading Languages (SHLs) in the databases of the four institutions

    Abstract
    Some members of the library community, including the Library of Congress Working Group on the Future of Bibliographic Control, have suggested that libraries should open up their catalogs to allow users to add descriptive tags to the bibliographic data in catalog records. The web site LibraryThing currently permits its members to add such user tags to its records for books and therefore provides a useful resource to contrast with library bibliographic records. A comparison between the LibraryThing tags for a group of books and the library-supplied subject headings for the same books shows that users and catalogers approach these descriptors very differently. Because of these differences, user tags can enhance subject access to library materials, but they cannot entirely replace controlled vocabularies such as the Library of Congress subject headings.

    Abstract
    Academic libraries have moved toward providing social networking features, such as tagging, in their library catalogs. To explore whether user tags can enhance access to individual literary works, the author obtained a sample of individual works of English and American literature from the twentieth and twenty-first centuries from a large academic library catalog and searched them in LibraryThing. The author compared match rates, the availability of subject headings and tags across various literary forms, and the terminology used in tags versus controlled-vocabulary headings on a subset of records. In addition, she evaluated the usefulness of available LibraryThing tags for the library catalog records that lacked subject headings. Options for utilizing the subject terms available in sources outside the local catalog also are discussed.

    Abstract
    Canada has a long history of adapting United States subject access tools, including the Library of Congress Classification (LCC), Library of Congress Subject Headings (LCSH), the Dewey Decimal Classification, and the Sears List of Subject Headings, to meet the specific needs of Canadians. This paper addresses the extensions to these American tools for English-speaking Canadians. While the United States and Canada have many similarities, differences exist that require changing terminology and providing greater depth and precision in subject headings and classification for specifically Canadian topics. The major effort has been for Library and Archives Canada (LAC) systematically to provide extensions for LCC and LCSH for use within its cataloging records. This paper examines the history and philosophy of these Canadian efforts to provide enhanced subject access. Paradoxically, French-speaking Canadians may have found it easier to start from scratch with the Repertoire de vedettes-matiere because of the difficult decisions for English-language tools on how much change to implement in an environment where most Canadian libraries use the American subject access tools. Canadian studies scholars around the world can use Canadian records, especially those maintained by LAC, to obtain superior subject access for Canadian topics even if they obtain the documents from other sources.

    Abstract
    Argues the need to provide additional access points in the cataloguing of popular culture materials in libraries which treat such collections as special collections. Provides a list of 8 general principles to apply in enhancing access to such materials through the catalogue (by increasing the number of appropriate headings), and illustrates how these principles might be implemented in two areas: motion pictures, radio and television and popular music

    Abstract
    Rules regarding cataloguing, subject headings, the way information in bibliographic records is organised and the catalogue's interface, or the way the screen is set up, are barriers to the use of online catalogues by children Describes the background to and implementation of a project to create a child orientation catalogue with a graphical user interface, or one that relies on pictures instead of text, within Denver Public Library in Colorado. Now called the Kid's catalog and commercially available from the Colorado Alliance of Research Libraries Co., the catalogue's software acts as a front end to a library's regular catalogue

    Abstract
    State of the art review of the historical development of information science as deemed to be covered by the particular interests of memebers of the American Society for Information Science, as defined as the representation, storage, transmission, selection, retrieval, filtering, and use of documents and messages. Arranges the references cited roughly according to the classification scheme used by Information Science Abstracts, and so uses the headings: background; information science; techniques and technology; information related behaviour; application areas; social aspects; education for information science; institutions; individuals; geographical areas; and conclusions

    Abstract
    Bibliographical problems caused by geographic names in subject vataloging are examnied with a view toward determining procedures for establishing correct headings when changes of name occur and deciding upon the type of provisions to be made in subject catalog maintenance. Examples of typical changes of geographic names in Africa and suggested information cards for the subject catalog are provided
