If more than one city is listed, you usually go with the first one, which is typically the "home" or flagship of the publisher.
If you cannot find a year of publication on the score itself, then look up the item in the library online catalog. If the year is listed there, use it. If the year is indicated as 19? then use that. Your librarian can help you with this.
Professors at DePauw prefer that foreign titles remain in original languages. If your score reads Le Nozze di Figaro, do *not* translate to The Marriage of Figaro. If your title page reads Klavier Konzert, then do *not* translate to Piano Concerto.
