What's the difference between multiple pop-ups of Lean Library notifications?

Lean Library notifications will pop up in the following cases:

• you are off campus (In this case, you need to connect to the campus network first);
• you are on campus, but the current webpage is not about academic resources;
• you have access to the resource on this webpage;
• an open access version of the resource on this webpage is found at another link;
• the resource on this webpage is found at another link available in our library collection;
• this resource is not available in our library collection, but you can request a document delivery service to get this article in your email inbox.
