Picture some German university's arthistory department, and its official title would be "Kunsthistorisches Institut". "Kunsthistorisch" is an adjective, and "kunsthistorisches" is its nominative case. Moreover, "kunsthistorisches" is the strong declension case which is used without a definite article.
Now when I'd like to refer to said department's bibliography rules in an English text, I would have to use the definite article "the", which would be at odds with the strong declension in the institution's German name.
Still, what would be the correct alternative,
- "...the bibliography rules of the 'Kunsthistorisches Institut'..." or
- "...the bibliography rules of 'Kunsthistorisches Institut'...",
or would I even have to adapt to the appropriate German declension case (genitive or dative)? (My instinct makes me shudder.)
