I just came upon an interesting article in the The Guardian entitled Space Women. Author Alice Rawsthorn profiles 7 highly successful women working in the world of commercial art and explores why it is that women succeed in contemporary art dealing. While the article was published back in October of 2006 it is definitely worth a read.
I came upon this article via Kathy Tyrrell's Squidoo Lens Artbusiness. Check out Tyrrell's Lens which is full of great resources for artists.
