Dear *, when trying to convince someone to just have a look on koha and think about switching to koha, I was asked, what installations of koha there are in Germany. I assume, there is one in Berlin, hi Dorian ;-), but are there more? I think they fear to have no community to talk to, with their existing system (Bibliotheca) they have annual user meetings and they can talk about with neighboured libraries. And BTW, I was also asked about the supported cataloguing system (I am a novice to this stuff ;-). The question was whether they would have to learn the AACR (Anglo American Cataloguing Rules) or whether they could use RAK (Regeln für die Alphabetische Katalogisierung). When googling for information about cataloguing rules I had the impression that there are many. Have cataloguing rules any impact on how to use koha? If there is an impact, then how can we cope with national cataloguing rules? Any ideas? Best wishes, Ralf
