ARTstor is a nonprofit digital library that provides more than one million images in the arts and sciences covering a wide range of historical, political, social, economic, and cultural documentation from prehistory to the present. ARTstor collections enable a wide range of users -- curators, scholars, educators, librarians, and students -- to teach and study with images in an online environment optimized for exploring visual content in new and exciting ways. This meeting will highlight ARTstor collections and platform features, and will also provide an update on Shared Shelf.
