To refresh/sync content, such as your Library, on NOOK Color and NOOK Tablet devices:
1. Press the NOOK button on the front of your device to access the "Quick Navigation Bar".
2. Tap "Library".
3. In the Library window, tap the sync icon (two curved arrows forming a circle) located in the lower left corner of the screen.
After syncing your Library, any content that you had begun reading will open to the more recently viewed page the next time it is accessed.
