[Koha] Migrating authorities

[Michael Kuhn]

Hi Thomas

Bibliographic and authority data both need to be in MARCXML but they 
have a different structure:

* https://www.loc.gov/marc/bibliographic/
* https://www.loc.gov/marc/authority/

You first need to load both kinds of data. After that what you are 
probably looking for is the script "link_bibs_to_authorities.pl".

More information on this and more topics about authorities you will find 
at https://bywatersolutions.com/news/authorities-town-hall-recap

Hope this helps.

Best wishes: Michael
