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