You probably already know that UD is a longtime subscriber to Artstor, but you may not know what Shared Shelf and Shared Shelf Commons (sometimes called “Artstor Commons”) are.
UDaily has just published an article about Artstor and Shared Shelf at UD that may answer some of your questions. The Visual Resources Center has been working with Artstor and the UD Library for years, so please feel free to contact me anytime if you need more information about any of these services!
