The ARTstor Digital Library is a nonprofit resource that provides over 1.5 million digital images in the arts, architecture, humanities, and sciences with an accessible suite of software tools for teaching and research.
You can get to it from the Walsh library home page.
Select Articles and Databases from the "Search a Lot" box in the middle of the page
Then select Databases A-Z (small print in the bottom of the box)
Click on the A tab and scroll down the page until you see ARTstor.
Click on the link to open the database.
If you are off-campus you will definitely need to make sure you access ARTstor this way or you will not be recognized as a Walsh student. The log-in to authenticate from off-campus will be the same log-in you use on any of the Walsh computers on campus.
