1356 If $mergeto is different, the biblio field will be linked to $mergeto.
1357 If $mergeto is missing, the biblio field is deleted.
1358
1359 MARCfrom is used to determine if a cleared subfield in the authority record
1360 should be removed from a biblio. MARCto is used to populate the biblio
1361 record with the updated values; if you do not pass it, the biblio field
1362 will be deleted (same as missing mergeto).
1363
1364 Normally all biblio records linked to $mergefrom, will be considered. But
1365 you can pass specific numbers via the biblionumbers parameter.
1366
1367 The parameter override_limit is used by the cron job to force larger
1368 postponed merges.
1369
1370 Note: Although $mergefrom and $mergeto will normally be of the same
1371 authority type, merge also supports moving to another authority type.
