There are two ways to read titles that are on your bookshelf.
Method one: From either the Audio Books or Audio Magazines folder, select the name of the title you would like to read. In doing this, books and magazines that have been downloaded will automatically open in the Now Reading screen.
Method two: Activate the Read Now button. To do so, enter the Book Details page for the title of the book or magazine you want to read. Select the Read Now button, located directly after the title’s information. See Section 3.1 for information on accessing a book or magazine’s Book Details page.
You cannot read a book that is in the process of downloading.
