I couldn’t find a discussion on this topic, but I think it needs some
attention. If you run a non-English version of Firefox, any bibliographies
you generate in Zotero will be in that non-English locale (see
http://www.zotero.org/support/infrequently_asked_questions#other_languages).
While that may make sense for the more ‘general’ styles like Chicago, it
doesn’t for most journal-specific styles. Most if not all users who prepare
a bibliography for Das Arztliche Laboratorium will expect it to appear in
german. Bibliographies prepared in the Yeast Journal style should default to
American English, or to British English in case of the British Psychological
Society style.
Couldn’t the info section of CSL be extended with an optional specification
of which language the bibliography should default to? Software (like Zotero)
may still be allowed to override that (as is currently possible,

but at least locale-specific styles would default to the correct language.
