The ARTstor Library includes approximately 800,000 images covering art, architecture and archeology. The Charter Collection documents artistic traditions across many times and cultures and embraces architecture, painting, sculpture, photography, decorative arts, and design as well as many other forms of visual culture. (See: What's in ARTstor for a more detailed description). ARTstor's software tools support a wide range of uses including: viewing and analyzing images through features such as zooming and panning, saving groups of images online for personal or shared uses, and creating and delivering presentations both online and offline.
