New Prospects for Library Authority Data

This document presents an overview of recent developments in authority data and unified resource discovery tools, particularly focusing on new MARC fields that enhance bibliographic access to various resources, including books, articles, and digital objects. Key topics include the introduction of 37X fields for better representation of authors and associated data, machine-actionable data principles, and the implications of authority file updates for libraries, scholars, and publishing professionals. Emphasizing the shift from traditional authority control to a more dynamic approach, the paper outlines proposed changes and the importance of structured metadata.

  9. Limitations of Undifferentiated NARs • Rejected from VIAF • Cannot link to access points in bib records • New 37X-38X fields cannot apply

  10. Implications of the Break Up • Minor change: • Permitting greater range of qualifying info • Liberalizing the requirement for unique headings for small segment of the authority file

  11. Implications of the Break Up • Major change: • Shift in nature of authority work: Primary aspect • before Heading Construction • now Differentiating Entities, Creating Identifiers • Shift in skill set needed • beforeKnowledge of Rules; Training Required • nowDifferentiating; Detecting Duplicate Entities • Opening up authority file to new contributors • beforeChiefly Libraries • nowScholars, Publishers, Rights Management Agencies
