Method(s) used to choose which authority to keep in case we found duplicates. <methods> is a string composed of letters describing what methods to use and in which order. Letters can be: date: keep the most recent authority (based on 005 field) used: keep the most used authority ppn: PPN (UNIMARC only), keep the authority with a ppn (when some authorities don't have one, based on 009 field)
Example: -m ppn -m date -m used Among the authorities that have a PPN, keep the most recent, and if two (or more) have the same date in 005, keep the most used.
Default is 'used'
limit the deduplication to SOME authorities only
Example: -where="authid < 5000" will only auths with a low auth_id (old records)
display verbose logging, can be repeated twice for more info
show usage information.
