In addition to the useful information that one finds in OCLC which might be on non-English and older records, this round of messages on 670s from such records leads me to mention how much help we've been getting recently from European national libraries. The French authority file is especially helpful since the records are in a style that closely parallels NACO, i.e., heading with date, alternate forms of name, nationality, life dates, affiliations, link to bibs, and (alas) gender. I have also used the German and Dutch national libraries many times, as well as the Biblioteca nazionale centrale di Firenze.

And you get to practice your French, German, Dutch, and Italian.
