Hi Robert: You may not have meant to dredge up a conundrum with your comment, but one does have to look at the authority records before controlling to them-- not rarely (albeit infrequently), I have had to change already-controlled headings to other forms because the persons associated with the bib. records were not the persons represented by the controlling authority records.
