Full title: Dictionnaire des facteurs d'instruments de musique en Wallonie et à Bruxelles du 9e siècle à nos jours. That translates to something like, "Dictionary of musical instrument makers in Wallonia and Brussels from the 9th century to the present day." While Google Books lists this as a "sample," several hundred pages of the dictionary are online. Yes, it's in French. It's about $52 on Amazon.com, if you want your own paperback copy.
Enjoy!
