How does the digital book compare with the original printed book?

The digital book has the same content as the original book, and in most cases the content has been updated with recent corrections. Some of the digital books also have built in hyperlinks. These hyperlinks allow you, with a single click, to move quickly and easily to your desired location in the book. We have placed hyperlinks on useful pages, such as quizzes, connecting the questions and answers. Our digital books also have bookmarks that allow you to move quickly to a particular chapter or subsection.
