ARTstor is a digital library of nearly one million images in the areas of art, architecture, the humanities, and social sciences with a set of tools to view, present, and manage images for research and pedagogical purposes.

The Digital Library serves users both within the arts and in disciplines outside of the arts. This includes historians of art and architecture and others engaged in the visual arts, as well as individuals in fields as diverse as American Studies, Anthropology, Asian Studies, Classical Studies, Literary Studies, Medieval Studies, Music, Religious Studies, and Renaissance Studies.

Boston University holds a site-wide license through Mugar Library which can be accessed directly online using a current Kerberos account. Any issues with ARTstor should be directed to librarians at Mugar Library.
