To save storage space on your NOOK Simple Touch, you can archive books and periodicals you're not currently reading.
Archiving retains the book or periodical in your account, but removes the title from your NOOK.
You can un-archive a title at any time, so your reading material is never lost. After a title is archived, you will not be able to read it until you un-archive the content.
Archiving a book or periodical:
1. On the Details page of the title to be archived, double tap the cover and then select Archive from the options. A dialog box opens, asking you to confirm.
2. Tap OK.
Un-archiving Books or Periodicals:
1. In the Library, pull down the category menu and select Archived. Your NOOK displays titles that you have archived.
2. Find the book you want to un-archive, and tap the Un-archive button next to its title. Your NOOK un-archives the book or periodical and downloads it to your Library.
If the book or periodical does not appear right away, tap the Sync button at the top of the Library screen to update your Library.
