Hi Michael, while the list result list for lists looks a lot like the catalog search results, it's not working quite the same. Instead of using Zebra, it's build with SQL. That means that the sorting does work differently as well. My guess would be it's using biblio.copyrightdate. I would check the contents of the columns and your Koha-to-MARC mappings for it. In 18.11 it's possible to map both 260$c and 264$c, but it's not done by default. Hope that helps, Katrin On 08.07.20 11:20, Michael Kuhn wrote:
Hi
We are working with Koha 18.11.05 on Debian GNU/Linux 8.
In our library we found in the OPAC it is not possible to sort public lists correctly by copyright date.
As far as I know sorting by copyright date would follow the content of MARC 008 position 7-10. But looking at an actual sorting we see the sorting is as follows
2018 2017 2016 2015 2015 2014 2014 2013 2011 2017 <-- here it starts getting wrong 2019 2018 2016 2018 2016 ...
Alle these records have correct content in MARC 008 and MARC 264$c.
Strangely we found if a record has content in MARC 260$c and 264$c it changes the sort order - even if only MARC 008 should be relevant for the sort order.
How can we achieve the correct sort order?
Best wishes: Michael
