Hi,
I ran into this site while looking for information. They have a huge collection of scanned printed matter including a lot of drawing on Chinese subjects. Like Chinese women, proverbs, utilities, fables, uniform, etc. The search I did was "Chinese" and I haven't yet tried anything else as I'm still stunned by all I found.
Anyway, I wanted to share this with you people and hope it's of use to you.
Bye, Ming-Hua
