1331 Merge biblios linked to authority $mergefrom (mandatory parameter).
1332 If $mergeto equals mergefrom, the linked biblio field is updated.
1333 If $mergeto is different, the biblio field will be linked to $mergeto.
1334 If $mergeto is missing, the biblio field is deleted.
1335
1336 MARCfrom is used to determine if a cleared subfield in the authority record
1337 should be removed from a biblio. MARCto is used to populate the biblio
1338 record with the updated values; if you do not pass it, the biblio field
1339 will be deleted (same as missing mergeto).
1340
1341 Normally all biblio records linked to $mergefrom, will be considered. But
1342 you can pass specific numbers via the biblionumbers parameter.
1343
1344 The parameter override_limit is used by the cron job to force larger
1345 postponed merges.
1346
1347 Note: Although $mergefrom and $mergeto will normally be of the same
1348 authority type, merge also supports moving to another authority type.
