    Abstract
    Libraries using the LCSH can increase the effectiveness of their subject access. This can be accomplished through one of four methods for applying an increased number of headings: the addition of subject headings in situations where none have been supplied by LC; the use of pattern secondary headings; the use of major + minor techniques; and the use of minor + major techniques. Each of these methods will provide additional subject access to supplement that produced by the Library of Congress

    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
    The paper looks at ways in which traditional classification and indexing tools have dealt with the relationships between constituent terms; variations in these are examined and compared with the methods used in machine searching, particularly of the Internet and World Wide Web. Apparent correspondences with features of index languages are identified, and further methods of applying classification and indexing theory to machine retrieval are proposed. There are various ways in which indexing and retrieval systems, both conventional and electronic, deal with the problem of searching for documents on a subject basis, and various approaches to the analysis and processing of a query. There appear to be three basic models; the taxonomic or structural system, in which the user is offered a map of the `universe of knowledge'; the language based system, which offers a vocabulary of the subject and a grammar for dealing with compound statements; and the mathematical model using the language of symbolic logic or the algebra of set theory

    Abstract
    This article provides an update on progress since the partial roll-out of FAST in 2015 at the British Library. It discusses developments to the product and the provision of community interaction with FAST via a FAST funnel, ensuring the vocabulary is robust and flexible enough to meet the continued needs of Legal Deposit workflows. It describes the planning and implementation methods used in rolling out FAST to the majority of cataloging workflows at the British Library leading to extensive training over the autumn of 2022.

    Abstract
    Using subject headings for Online Retrieval is an indispensable tool for online system desingners who are developing new systems or refining exicting ones. The book describes subject analysis and subject searching in online catalogs, including the limitations of retrieval, and demonstrates how such limitations can be overcome through system design and programming. The book describes the Library of Congress Subject headings system and system characteristics, shows how information is stored in machine readable files, and offers examples of and recommendations for successful methods. Tables are included to support these recommendations, and diagrams, graphs, and bar charts are used to provide results of data analyses.

    Abstract
    This article presents an Italian experience of developing streamlined semantic interoperability between the Italian Thesaurus of Nuovo soggettario and the Library of Congress Subject Headings (LCSH). This ongoing project must take into consideration the differences between the two indexing tools, while the criteria on which the resulting actions are based are being clarified continually. Reciprocal interoperability, thanks to the Simple Knowledge Organization System format, enables us to create links with English language subject headings. The National Central Library of Florence is studying methods of automatically catching LCSH equivalents and the question of how to take advantage of both Semantic Web outputs and the multilingual dataset of Wikidata.

    Abstract
    Reports an algorithmic approach to the automatic generation of thesauri for electronic community systems. The techniques used included terms filtering, automatic indexing, and cluster analysis. The testbed for the research was the Worm Community System, which contains a comprehensive library of specialized community data and literature, currently in use by molecular biologists who study the nematode worm. The resulting worm thesaurus included 2709 researchers' names, 798 gene names, 20 experimental methods, and 4302 subject descriptors. On average, each term had about 90 weighted neighbouring terms indicating relevant concepts. The thesaurus was developed as an online search aide. Tests the worm thesaurus in an experiment with 6 worm researchers of varying degrees of expertise and background. The experiment showed that the thesaurus was an excellent 'memory jogging' device and that it supported learning and serendipitous browsing. Despite some occurrences of obvious noise, the system was useful in suggesting relevant concepts for the researchers' queries and it helped improve concept recall. With a simple browsing interface, an automatic thesaurus can become a useful tool for online search and can assist researchers in exploring and traversing a dynamic and complex electronic community system
