If it’s not showing in your Nook library, check your library settings to make sure you have it set to Show Downloaded ePubs.

Depending on your device, the setting may be in one of three places:

• In the Nook app, go to Settings, then Library. Make sure Show Downloaded ePubs is checked.
• On Nook tablets, go to your Nook Home and tap the menu button (it looks like three horizontal lines) and choose Settings, then tap Library and make sure Show Downloaded ePubs is checked.
• On Nook tablets, you may have a Nook Settings app. If so, open Nook Settings, tap Library, then check to make sure the Show Downloaded ePubs is ticked.

Go back to your Nook library and your book should appear.
