I'm almost code-illiterate, but something seems fishy here. I was checking the new Encore OPAC system at Warsaw's National Library. It works great with Zotero: a book is correctly identified as a book, all the fields get imported correctly, it works like a charm. When I export the citation from Zotero using the native Wikipedia exporter, it looks like this:
{{Cite book| publisher = Wydawnictwo Wyższej Szkoły Przedsiębiorczości i Zarządzania im. Leona Koźmińskiego| isbn = 8389437503| last1 = Jemielniak| first1 = Dariusz| last2 = Latusek-Jurczak| first2 = Dominika| title = Zarządzanie: teoria i praktyka od podstaw: ćwiczenia| location = Warszawa| date = 2005}}
But using the very same link with Citoid returns a cite web template (or its' equivalent @ plwiki) filled with
"Exception". katalogi.bn.org.pl. Retrieved 2015-08-12.
The "Exception" links to this error page.
If I understand correctly, Citoid uses the very same translators Zotero does, so all links working in Zotero should also work in Citoid. Why aren't they?
