CDL OA eBook title duplication.
From CDL e-resources Acquisitions. Summarized email from cdlacq on Sept 21, 2022:CDL turns on full yearly CZ collections.
If publishers add some open access titles to either the yearly CZ frontlist collections or give them to us when we receive marc records for our package, then those titles may end up duplicating titles from the same publisher under a full Open Access collection that we have turned on in the NZ.
We determined that this is ok to leave as they are for now, for the sake of staff time & making collections available to users faster in the NZ, compared to the work it would take to clean them up now or prior to processing a new collection. This is not exactly a new issue. We may consider internally whether there are ways we can try to mitigate this going forward, in the future when we have more capacity for this.

Vendor-supplied, non-provider-neutral, non-OCLC record duplication. Like those from Cassidy cataloging for resources in Westlaw and LexisNexis.
13,700 bibs in UCI Law Westlaw collection
16,650 MMS IDs for Distinct count MMS ID where the Title + Author Combined and Normalized match
Example: separate, non-provide-neutral, non-OCLC bib records for every law review in Lexis & Westlaw
Electronic record duplication when campuses use different record sets. For example, UCI Law is using OCLC records for an eBook package without vendor-supplied records, which is time-consuming but gets us the OCLC updates. But another campus is using non-OCLC CZ records. Both of those sets of records have linked NZ bibs.
MARCIVE government document records. It’s known that there are duplicative records in the system.
