UC Libraries | Determinations around what and how we report are for the most part managed/owned by the UC Libraries (i.e., shared ownership). |
CDL | CDL analysts, who are responsible for constructing report queries at the Network Zone according to templates agreed upon by the UC Libraries, must exclude items based a variety of parameters… |
Reasoning
Background
System-wide, some duplication exists in title-level records. Cataloging rules provide guidance about when separate title-level records are required and when campuses should use the same bibliographic record to represent multiple items. However, in practice, bibliographic records are duplicated with some regularity, especially for electronic materials. For example:
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.
Sample: Ex Libris Discovery - 9780806192116 (exlibrisgroup.com)
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.
Options Considered
ARL instructions for title counts :
Report the total number of titles managed and maintained by the library that are cataloged and made ready for use.
Deduplicate titles by counting multiple copies of the same manifestation as one title.
Identical content in different formats should not be deduplicated, and each format should be counted as a different title. For example, a serial title available in print, microform and online would be counted as three titles.
Count different editions and versions of the same work as separate titles since they denote depth in the collection.
Counting the 245 field when the library provides stewardship for those resources may be sufficient.
Alma Options | Notes |
|---|---|
Title Normalized, separated by format | This undercounts unique titles because works with different authors and editions are not distinguished. |
Title Author Combined and Normalized, separated by format | This undercounts unique titles because works in different editions are not distinguished |
MMS ID | This overcounts unique titles. |
