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 before Knowledge of Rules; Training Required now Differentiating; Detecting Duplicate Entities – Opening up authority file to new contributors before Chiefly Libraries now Scholars, Publishers, Rights Management Agencies
