The old problem: UNIMARC uses biblio.publicationyear, MARC21 uses
biblio.copyrightdate. Patch adds a fallback, if there is nothing
in publicationyear, copyrightdate will be displayed.
To test:
- In a MARC21 database
- Add a new subscription
- Search for records
- Verify the publication year column remains empty
- Apply patch
- Repeat search
- Verify that the year now shows
