 772 Returns a hashref with a summary of the specified record.
 773
 774 Comment : authtypecode can be inferred from both record and authid.
 775 Moreover, authid can also be inferred from $record.
 776 Would it be interesting to delete those things.

1338 If $mergeto is different, the biblio field will be linked to $mergeto.
1339 If $mergeto is missing, the biblio field is deleted.
1340
1341 MARCfrom is used to determine if a cleared subfield in the authority record
1342 should be removed from a biblio. MARCto is used to populate the biblio
1343 record with the updated values; if you do not pass it, the biblio field
1344 will be deleted (same as missing mergeto).
1345
1346 Normally all biblio records linked to $mergefrom, will be considered. But
1347 you can pass specific numbers via the biblionumbers parameter.
1348
1349 The parameter override_limit is used by the cron job to force larger
1350 postponed merges.
1351
1352 Note: Although $mergefrom and $mergeto will normally be of the same
1353 authority type, merge also supports moving to another authority type.
