I think the AIC website is 4. The best part of the website is the organization. I can clearly search the information I need. The website have the photocopy of every single artwork they have, and they put them in different styles. I chose the Picasso's painting in my collection. That work is a typical cubism art work. It located in the modernist area. I can also search the artwork by the artist. I see that the art institution have plenty of artwork worldwide.
