I know the feeling of being swamped with mail EEEKK!!
I don't know of any web sites but I would love it if you forwarded to
me any you hear about. What I can recommend is a good text. A
History of Far Eastern Art by Sherman Lee I know that Amazon at
amazon.com do have it. It is a great information source on Indian
Art and actually Chinese and Japanese too!
