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.)
