+The E-book Viewer
+=============================
+
+|app| includes a built-in E-book viewer that can view all the major e-book formats. 
+The viewer is highly customizable and has many advanced features. 
+
+.. contents::
+    :depth: 1
+    :local:
+
+Starting the viewer
+--------------------
+
+You can view any of the books in your |app| library by selecting the book and pressing the View button. This
+will open up the book in the e-book viewer. You can also launch the viewer by itself, from the Start menu in windows
+or using the command :command:`ebook-viewer` in Linux and OS X (you have to install the command line tools on OS X
+first by going to Preferences->Advanced).
+
+Navigating around an e-book
+-----------------------------
+

+
+.. |toci| image:: images/toc.png
+
+.. |navposi| image:: images/nav_pos.png
+
+.. |refmi| image:: images/ref_mode_button.png
+
+
+You can "turn pages" in a book by using the :guilabel:`Page Next` and :guilabel:`Page Previous` buttons |pni|, or by pressing
+the Page Down/Page Up keys. Unlike most e-book viewers, |app| does not force you to view books in paged mode. You can
+scroll by amounts less than a page by using the scroll bar or various customizable keyboard shortcuts. 
+
+Bookmarks
+^^^^^^^^^^^^
+
+When you are in the middle of a book and close the viewer, it will remember where you stopped reading and return there
+the next time you open the book. You can also set bookmarks in the book by using the Bookmark button |bookmi|. When viewing EPUB format
+books, these bookmarks are actually saved in the EPUB file itself, so you can add bookmarks, then send the file to a friend and
+when they open the file, they will be able to see your bookmarks.
+
+Table of Contents
+^^^^^^^^^^^^^^^^^^^^
+
+If the book you are reading defines a Table of Contents, you can access it by pressing the Table of Contents button |toci|.
+This will bring up a list of sections in the book and you can click on any of them to jump to that portion of the book.
+
+Navigating by location
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+E-books, unlike paper books have no concept of pages. Instead,
+as you read through the book, you will notice that your position in the book is displayed in the upper left corner in a box
+like this |navposi|. This is both your current position and the total length of the book. These numbers are independent of the screen size and font
+size you are viewing the boko at, and they play a similar role to page numbers in paper books.
+You can enter any number you like to go to the corresponding location in the book. 
+
+|app| also has a very handy
+reference mode. You can turn it on by clicking the Reference Mode button |refmi|. Once you do this, every time you move your
+mouse over a paragraph, calibre will display a unique number made up of the section and paragraph numbers. 
+
+.. image:: images/ref_mode.png
+
+You can use this number to unambiguously refer to parts of the books when discussing it with friends or referring to it
+in other works. You can enter these numbers in the box marked Go to at the top of the window to go to a particular
+reference location. 
+
+If you click on links inside the e-book to take you to different parts of the book, like an endnote, you can use the back and forward buttons 
+in the top left corner to return to where you were. These button behave just like those in a web browser. 
+
+Customizing the look and feel of your reading experience
+------------------------------------------------------------
+
+.. |fontsizei| image:: images/font_size.png
+
+.. |fsi| image:: images/full_screen.png
+
+.. |prefbi| image:: images/pref_button.png
+
+You can change font sizes on the fly by using the font size buttons |fontsizei|. You can also make the viewer full screen
+by pressing the Full Screen button |fsi|. By clicking the Preferences button |prefbi|, you can change the default fonts used 
+by the viewer to ones you like as well as the default font size when the viewer starts up. 
+
+More advanced customization can be achieved by the User Stylesheet setting. This is a stylesheet you can set that will be applied
+to every book. Using it you can do things like have white text on a black background, change paragraph styles, text justification, etc.
+For examples if custom stylesheets used by |app|'s users, see `http://www.mobileread.com/forums/showthread.php?t=51500`_.
+
+Dictionary lookup
+-------------------
+
+You can lookup the meaning of words in the current book by right clicking on a word. |app| uses the publicly available dictionary
+server at ``dict.org`` to lookup words. The definition is displayed in a small box at the bottom of the screen. 
+
+Copying text and images
+-------------------------
+
+You can select text and images by dragging the content with your mouse and then right click to copy to the clipboard.
+The copied material can be pasted into another application as plain text and images.
+
