Since the currently popular suspicion is that an 049 $c plus
re-indexing of the bib record creates phantom holdings, I tried a
further test.
I found a personal author (author A) who was attached to only one bib
record, with that bib record having an 049 $c.
I made Author A a cross reference on the authority record for Author
B. On the bib record, I changed the personal name heading from Author
A to Author B.
After filing the bib record, there were phantom holdings.
***Notice I said plural holdings. Everytime experiment I had
conducted so far resulted in two phantom holdings.***
I wondered what would happen if I didn't involve the authority file.
I found another bib record with an 049 $c. I changed Author C on the
bib record to another legitimate author, Author D. I filed the bib
record and got *one* phantom holding.
So it would seem that if only the bib file is involved you get one
phantom holding; if the authority file and the bib file are involved
you get two phantom holdings.
