Script to merge an authority into another
|
|
parameters :
|
|
\th : this version/help screen
|
|
\tv : verbose mode (show many things on screen)
|
|
\tf : the authority number to merge (the one that can be deleted after the merge).
|
|
\tt : the authority number where to merge
|
|
\tn : don't ask for confirmation (useful for batch mergings, should not be used on command line)
|
|
|
|
All biblios with the authority in -t will be modified to be "connected" to authority -f
|
|
SAMPLE :
|
|
./merge_authority.pl -f 2457 -t 531
|
|
|
|
Before doing anything, the script will show both authorities and ask for confirmation. Of course, you can merge only 2 authorities of the same kind.
