ARTstor is a non-profit organization created by The Andrew W. Mellon Foundation. As part of its ongoing effort to become a community resource, ARTstor is developing a rich digital library that will offer coherent collections of art images and descriptive information as well as the software tools to enable active use of the collections. The ARTstor Library's initial content will include approximately 300,000 images covering art, architecture and archeology. ARTstor's initial software tools will support a wide range of pedagogical and research 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.
