I recently borrowed and read two e-books from my local library.  They have expired, and no long show up in my online account with my library.  However, they are still showing up on my Nook Simple Touch under the "Library" section even though the lending period has expired.  How can I delete them from my Nook?  Thanks.

There should be an option to delete them while you are on the book details.  But I usually manage them while on my computer. 

They may well show up on your eReader.  But they are probably scrambled, if they are in an Adobe format.  I know I see them but cannot open them.

Open up Adobe Digital on your computer.

Hook up the Nook.

Go to the Nook on the Adobe Digital Screen.

Hover over the book title you want to remove. A drop down box should appear.

Click "return item"

I also do the "all items" and "return item" as I like to keep the Adobe clean as well.

If you finish a book early and want to return it before the due date, use this same process.

Thank you both.  I figured it had to be something easy like that.

Overdrive is a very common platform for libraries to use. This is linked to Adobe. Adobe lets the library include an expiration date on the book, where it becomes scrambled after that date.

Some libraries have started using another program, by 3M? In addition, I think there is now a way for some eReaders to link directly to the library system, probably through an Overdrive app.

I manage mine on my computer.

Yup. The Nook Tablet bypasses the whole Adobe deal and uses an app. I haven't played with it yet. But those of us with a SImple Touch have to do it the old fashioned route and it's really not that big of a deal.

And the Kindle books have to be deleted on the Amazon website.  Any time I select one of the expired Kindle books, these ads to buy it from Amazon pop up. 

Poor librarians.  Having their data used to try and sell books.
