  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
