"The Art Renewal Center"
"The purpose of the Art Renewal Center is to create the largest art museum on the internet. The goal is to include hundreds of thousands of oversized high quality images of all the known works of the greatest painters and sculptors in human history. Each work is cross referenced to the largest online encyclopedic art reference library of historical texts, essays, biographies and articles."
In other words -- as an artist myself -- I've just come across THE goldmine for investigating historic artwork on the internet. This is really cool! It's like coming across the mother of all art history books -- but online. Yeah, this one's getting bookmarked!
