If you access Artstor from on campus at library.artstor.org, the database will recognize your IP address as belonging to a subscribing institution and you will be granted access automatically and be able to search and view images. However, to download images you must register for an account. With a registered account you can also curate groups of images, share them, and download them directly into PowerPoint presentations.
There are two ways to register for an Artstor account:
After you have registered for an account, you will have 120 days of remote access. After 120 days you will need to log in to Artstor from a computer on campus--or through your library’s proxy--in order to reset your remote access for another 120 days.
If you visit library.artstor.org and see this screen, you do not have IP-based access and must log in with your registered account.
