=head1 DESCRIPTION |
| 60 |
|
| 61 |
This batch job finds every authority ID in the Koha-Auth-Number index, |
| 62 |
and then it runs a "merge", so that all bibliographic records using |
| 63 |
that authority will have their headings updated from the authoritative |
| 64 |
source record. |
| 65 |
|
| 66 |
This is a useful job to run after link_bibs_to_authorities.pl. |
