Planning a batch authority control project — questions Are there already authority records in the database? If so, do you care about them? Is there other work worth tacking on to the project? Exporting and reloading all of your bib records can be time consuming, so adding on additional data changes (e.g., RDA enrichment) can make sense Deduplication?

Selecting records to export “Nearly everything” Exceptions can include Brief acquisitions records Brief circulation records Brief records for paperbacks Electronic resource records that get reloaded anyway Deleted records

Scheduling General sequence is Cataloging freeze Export Transfer Process Fetch Re-import Cataloging freeze

Exporting For small databases, can use Vandelay

Exporting For larger databases, use the command line:
