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.
