1) Choose the authority record to retain when there are duplicates by following the following order of priority:
<span style="color:red">'''Step 1: Selection'''<br>
''Situation 1 :'' Duplicates between migrated records, and LAC records which existed before the migration (June, 2 2020).</span>
Choose the authority record to retain when there are duplicates by following the following order of priority:
<span id="046$u$v"></span><ol>
<li>Prefer a record that already has a 016 field over one that does not.</li>
<li>Prefer a LAC record over a record from BAnQ or universities. </li>
<ol><span style="color:red">''Note for PFAN:'' If there is more than one LAC record among the duplicates, report them to LAC by emailing the OCLC control numbers to bac.pfansuppression-deletionfnap.lac@canada.ca and with the subject line: LAC Duplicates. LAC will determine which record will be retained and delete the LAC record(s) not retained. If duplicates also include records from other participants, follow steps 2 and 3 below once LAC has identified which record to retain.
<br>
''Note for LAC:'' If there are more than one LAC records among the duplicates, the cataloguer has to determine which record will be kept, and he/she must delete the other records. The oldest record will usually be preferred. Do not forget to do any bibliographic file maintenance (including the LBD), as required.</span> </ol>
<li>Prefer a record from BAnQ over a record from universities. <span style="color:red">''Note for PFAN and LAC :'' University records have a code other than CaOONL or CaQMBN in field 040 $a.</span>
</li>
<li>Prefer an RDA record over a non-RDA record.
<li>Prefer a more complete record over one that is less complete.</li>
