Artcyclopedia: The Fine Art Search EngineThe mission of this Web site "is to become the definitive and most effective guide to museum-quality fine art on the Internet." And it is an excellent resource! Only provides references to sites on the Web where artists' works can be viewed online.
Focus is primarily on painting and sculpture, but the Web site also includes other artistic media where possible, including photography, decorative arts, installation art, video, digital and web-based art, naïve art/folk art/outsider art, and architecture. The site is primarily oriented toward searching by artist name.
