1384 [ biblionumbers => [ $a, $b, $c ], ]
1385 [ override_limit => 1, ]
1388 Merge biblios linked to authority $mergefrom (mandatory parameter).
1389 If $mergeto equals mergefrom, the linked biblio field is updated.
1390 If $mergeto is different, the biblio field will be linked to $mergeto.
1391 If $mergeto is missing, the biblio field is deleted.
1393 MARCfrom is used to determine if a cleared subfield in the authority record
1394 should be removed from a biblio. MARCto is used to populate the biblio
1395 record with the updated values; if you do not pass it, the biblio field
1396 will be deleted (same as missing mergeto).
1398 Normally all biblio records linked to $mergefrom, will be considered. But
1399 you can pass specific numbers via the biblionumbers parameter.
1401 The parameter override_limit is used by the cron job to force larger
1404 Note: Although $mergefrom and $mergeto will normally be of the same
1405 authority type, merge also supports moving to another authority type.
