Abstract

This article describes the project to build the initial International Standard Name Identifier (ISNI) database by deploying the techniques used to develop the Virtual International Authority File (VIAF). It focuses particularly on the work of the OCLC team in transforming the VIAF "resource file" model of matched data into a robust, operational, and authoritative file of uniquely assigned ISNIs as a base for an ongoing ISNI assignment system, and on the quality assurance validation of the database provided by the British Library and the Bibliothèque nationale de France. The need for future interaction between ongoing ISNI assignment and name authority control in libraries is also explored.

Abstract

The Mollie Thomson Memorial Lecture given to the Cataloguers' Section of the Australia Library and Information Association at the State Library of New South Wales, 18.10.89. Considers the success of developments in authority control in commercially available library housekeeping systems and what still needs to be achieved. Sets out the reasons why authority control is necessary and examnines the current situation under the folowing headings: making authority data available; authority control and the Australian Bibliographic Network; authority MARC output; the provision of clean data; the allowance of flexibility in varying Library of Congress Subject Headings (LCSH); providing relief from the time consuming manual work; the 'Superchange' enhancement; the 'Subdivision Mapping' enhancement; possible changes to the MARC authorities format; and the readiness of local systems to employ MARC authority data

Abstract

WorldCat records are clustered into works, and within works, into content and manifestation clusters. A recent project revisited the clustering of collected works that had been previously sidelined because of the challenges posed by their complexity. Attention was given to both the identification of collected works and to the determination of the component works within them. By extensively analysing cast-list information, performance notes, contents notes, titles, uniform titles and added entries, the contents of collected works could be identified and differentiated so that correct clustering was achieved. Further work is envisaged in the form of refining the tests and weights and also in the creation and use of name/title authority records and other knowledge cards in clustering. There is a requirement to link collected works with their component works for use in search and retrieval.
