By default, when you are using the Web browser or reading certain magazines, your NOOK device* switches orientation automatically when rotated. That is, if you turn your NOOK so that its left edge becomes the bottom edge of the screen, your NOOK switches from portrait mode to landscape mode. Tap the Orientation checkbox to turn this rotation feature on or off.
NOTE: Kids Picture Books always open in landscape mode.
*This does not apply to NOOK SimpleTouch or NOOK Glowlight reading devices.
