Here's another link from my neck of the woods. A very comprehensive page
of links to music publishers all over the world, many with on-line

It is maintained by LLorenc Balsach of Barcelona, who also runs two cd
labels, one devoted solely to Catalan composers, and his entire site is
worth an explore, though some is only in Catalan.
