troubadour poetry

[jsdb]

I'm very ignorant of troubadour poetry: its predecessors and its descendents. I'm not even aware of what languages it used (besides provencal). Are there good books about this--history and poetry? All I know is that perhaps it was given form by spanish arabian influence?
thanks,

on the other hand, if anyone is in a position to enlighten me himself, that would be wonderful. web sites too...
