Scores from Collected Editions
Use the title page in your volume to gain information such as Series, Workgroup, editor(s), etc. Keep titles in their original language and italicize. Use sentence style capitalization--for example, in German, nouns are capitalized, verbs and adjectives are not.
After the title, go ahead and translate foreign terms to English.
Roman numerals with regular numbers: Series 2, NOT Series II.
If there is more than one city listed, choose the first one. "Vorgelegt von" or "herausgegeben von" (edited by) is where you locate editor names.
You'll notice that Series and Workgroup often have accompanying genres/titles.
