A question.

I'm looking for information about the writing of baroque styled music. I already know all about the forms of music, the basso continuo and such..., the general knowledge And now I seek to deepen my interest further to a more advanced level.

Is there perhaps any useful sources on the web? Or is it that this kind of specialists literature only exists in physical form?

ps. pantent pending on the title! Could make a good name for a musical piece.
