Artstor
A personal account is required to access many features, including course content posted by instructors in personal collections.
Artstor is a digital image library of over 2 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. Artstor digitizes and provides high-quality digitized images from numerous museums, academic institutions, and private foundations. Artstor is hosted on the JSTOR platform, so Artstor images are also findable in JSTOR platform-wide searches.
Many features are only available if you register for a personal account. Registering for a personal account will allow you to download images, save images into groups, share your groups with other registered users, view groups created by other users (such as collections set up by course instructors), add notes to individual images, set personal display options, and export citations.
