If OCLC included a substantial number of "Jackson, Tom" headings controlled by the n 50027953 authority, one could make a case for changing its 100 to "Jackson, Tom, 1932-" (with the related name/title NARs) and deleting the other authority to resolve the conflicts and take advantage of OCLC's automated updating functionality. But I haven't found any of the many relevant bib records controlled by the undated authority.

On the other hand, all the OCLC bib records for "Jackson, Tom, 1932-" are controlled by their authority, so in terms of dynamic relation to the bib file, that authority is more important.

What I wound not do is add "400 1 $a Jackson, Tom $w nne" to the more recent authority. In our Alma catalog, that would have the effect of changing all our "Jackson, Tom" headings to "Jackson, Tom, 1932-", which we would prefer not to see happen. Likwewise, eliminating the authority for an undated heading in a case like this would be better for catalogs like ours.  Changing the existing heading by adding the date would add the date willy-nilly to all our "Jackson, Tom" authors, since Alma automatically controls them (where OCLC does not.)

I agree with you. Even though n 50027953 isn't coded as undifferentiated it might as well be since you have discovered that in the bib file the access point has been used to represent more than one person.

My opinion only, of course.

If you do choose to keep nb2011032496 and have n 50027953 canceled, don't forget that there are some related NARs that will also need revision.

This seems to be my week for finding duplicates.  NAR n  50027953 is for Jackson, Tom, no dates, but still unique.  NAR nb2011032496 is for Jackson, Tom, 1932-.  These individuals are the same person, having written the same book, with a different title in Britain.  There seem to be a great many records with the heading Jackson, Tom [no dates], but some of these seem not to be the Tom Jackson who writes books on how to get a job.  But there seem to be far fewer records with the heading that includes the date.  Still, because there are bib records which have headings with no date for a different Tom Jackson, I think it would be better to use the heading with the date as the authorized form, even though the form without the date was established earlier.  What is the opinion of this forum?
