[Koha] eBook marc records and subject headings

[clint.deckard]

Greetings all,
I have had a query from a school that receives brief marc records from 
their eBook vendor that do not contain subject headings but have an 
embedded url with online authorisation; they also have a subscription 
with a cataloguing company (SCIS in Australia) that can provide (some) 
full records with subject headings for eBooks. I am trying to determine 
the best workflow to add subject headings and would appreciate any 
advice or suggestions. At the moment I can only come up with adding the 
subject headings manually, one item at a time which is not ideal.

Many thanks,
Clint Deckard.
