[Koha] authority files -- does anyone have them?

[Christine Forte]

dear friends,

i'd be interested in hearing from anyone who has downloaded, created, or
purchased authority files for their catalog. 

(is everyone getting by just fine w/o them?) 

i like to see the authority lists for subjects, because i find it can help
or inspire my searches, but  maybe the trend is that authority files are
slowly becoming obsolete.

best regards,
christine
