Merge biblios linked to authority $mergefrom (mandatory parameter).
|
|
If $mergeto equals mergefrom, the linked biblio field is updated.
|
|
If $mergeto is different, the biblio field will be linked to $mergeto.
|
|
If $mergeto is missing, the biblio field is deleted.
|
|
|
|
MARCfrom is used to determine if a cleared subfield in the authority record
|
|
should be removed from a biblio. MARCto is used to populate the biblio
|
|
record with the updated values; if you do not pass it, the biblio field
|
|
will be deleted (same as missing mergeto).
|
|
|
|
Normally all biblio records linked to $mergefrom, will be considered. But
|
|
you can pass specific numbers via the biblionumbers parameter.
|
|
|
|
The parameter override_limit is used by the cron job to force larger
|
|
postponed merges.
|
|
|
|
Note: Although $mergefrom and $mergeto will normally be of the same
|
|
authority type, merge also supports moving to another authority type.
