Another scenario is when it is a library book (or eBook). Click on the "Access options" button and then go to "Retrieve Catalog Item."
The link will then take you to the library catalog. If it is a physical book, you can note down the call number and find it on the shelf (or you can place a hold on it and pick it up at the library!). If it is an eBook, you will be able to access immediately.
