Bye bye ebook

This morning, the time was up on my borrowed ebook. When I went into my computer and clicked on the icon for the book, it said that the file could not be found, because the license for the book had expired. When I turned on my nook and clicked on the title, it said the same thing.

Technology is very smart and efficient.

So will the titles automatically disappear from my nook or do I have to delete them? And how do I do that?

Now to get my hands on a New York Public Library card, because they have far more ebooks I can borrow with shorter waiting periods.
