Abstract

Authority files have played an important role in improving the quality of indexing and subject cataloging. Although authorities can significantly improve search by increasing the number of access points, they are rarely an integral part of the information retrieval process, particularly end-users searches. A retrieval prototype, searchFAST, was developed to test the feasibility of using an authority file as an index to bibliographic records. searchFAST uses FAST (Faceted Application of Subject Terminology) as an index to OCLC's WorldCat.org bibliographic database. The searchFAST methodology complements, rather than replaces, existing WorldCat.org access. The bibliographic file is searched indirectly; first the authority file is searched to identify appropriate subject headings, then the headings are used to retrieve the matching bibliographic records. The prototype demonstrates the effectiveness and practicality of using an authority file as an index. Searching the authority file leverages authority control work by increasing the number of access points while supporting a simple interface designed for end-users.

Abstract

The paper provides an illustration of the benefits of subject authority control improving multilingual subject access in NEBIS - Netzwerk von Bibliotheken und Informationsstellen in der Schweiz. This example of good practice focuses on some important aspects of classification and indexing. NEBIS subject authorities comprise a classification scheme and multilingual subject descriptor system. A bibliographic system supported by subject authority control empowers libraries as it enables them to expand and adjust vocabulary and link subjects to suit their specific audience. Most importantly it allows the management of different subject vocabularies in numerous languages. In addition, such an enriched subject index creates re-usable and shareable source of subject statements that has value in the wider context of information exchange. The illustrations and supporting arguments are based on indexing practice, subject authority control and use of classification in ETH-Bibliothek, which is the largest library within the NEBIS network.

Abstract

The paper introduces TinREAD (The Information Navigator for Readers), an integrated library system produced by IME Romania. The main feature of interest is the way TinREAD can handle a classification-based thesaurus in which verbal index terms are mapped to classification notations. It supports subject authority control interlinking the authority files (subject headings and UDC system). Authority files are used for indexing consistency. Although it is said that intellectual indexing is, unlike automated indexing, both subjective and inconsistent, TinREAD is using intellectual indexing as input (the UDC notations assigned to documents) for the automated indexing resulting from the implementation of a thesaurus structure based on UDC. Each UDC notation is represented by a UNIMARC subject heading record as authority data. One classification notation can be used to search simultaneously into more than one corresponding thesaurus. This way natural language terms are used in indexing and, at the same time, the link with the corresponding classification notation is kept. Additionally, the system can also manage multilingual data for the authority files. This, together with other characteristics of TinREAD are largely discussed and illustrated in the paper. Problems encountered and possible solutions to tackle them are shown.
