Hello. From what I know, Zotero supports central repositories from US Library of Congress, French national library and German national library. There are however other nations in Europe that would benefit from their central repositories being included in this system, including Czech Republic. Czech National Library, Czech National Technical Library and other national libraries would be great, and for Czech Wikipedia actually very much useful and welcome. Let's not end up here. Connecting up entirety of Europe wouldn't be bad, I would also throw in British national libraries, as British Islands are also part of Europe, so that would make sense. Are there plans to connect up the rest of Europe and possibly the rest of the world?
Topic on Talk:Citoid/Creating Zotero translators
There is a task for Czech specifically in https://phabricator.wikimedia.org/T208991
And some broader discussion here: https://phabricator.wikimedia.org/T336298#8894492
And a general ticket here: https://phabricator.wikimedia.org/T212585
And someone has already contributed on for Polish national library here (although it is pending merge) but there is some relevant discussion there as well: https://github.com/zotero/translators/pull/3036
Thank you.
