Subject: [Koha] Looking for z39.50-servers

Hi!

Most of our books are Danish and i have a handful of very good z39.50-servers, where I can find them for cataloguing.

However, in the library we also have a few German and English books. It is mainly children's books. I know:

http://irspy.indexdata.com/

and I have tried to find English and German servers there, but i wonder if somebody has an advice as to which server to use? I think it should be a big public library, where the server works well.
