Does the nook e-book tell you what page on?

Yes, the Nook e-reader will tell you what page you are on. Here's how it typically works:

* Page Number Display: The Nook will usually display the current page number at the bottom of the screen.

* Progress Bar: Most Nook models also have a progress bar at the top or bottom of the screen, which shows your overall progress through the book.

* Percentage Read: Some Nook models may also display the percentage of the book you have read.

Note: The exact way the page information is displayed may vary slightly depending on the specific Nook model you have.
