Our Review:

Nook is an eBook app by Barnes & Noble. You must have a Barnes & Noble account to use the app. Every user automatically gets five or six free ebooks when they sign in. The books are classics such as: Little Women, Pride and Prejudice, Dracula, etc.

The layout is very similar to other book apps. When you open a book, there are several buttons on the page. You can control the brightness; text size; select Normal, Night, or Sepia themes; choose different fonts; search for words and page numbers; and make bookmarks.

Unlike iBooks and Kindle, the Nook app lets you control the line spacing; margin size; and whether to turn justification on/off and also publisher's defaults. Justification is the process of making the letters at the right or left edge of a printed page form a straight line. I turned on publisher's defaults, but it only seems to change the shape of the text.

The Nook app supports ePub and PDF formats.
