How URL’s fail User's library doesn't subscribe to target target authenticates by IP, user is off campus User's library gets target item in a full-text aggregation User's library has a locally hosted copy of target journal User's country has a nationally hosted copy of target journal target has moved its content without telling source target has become a porn site This is known as the "Appropriate Copy Problem" URL source target User
