How to build HTML5 e-Reader?
I've been looking at the recent HTML5 e-Readers. The best in this field now are:
<ul>
<li><a href="http://books.google.com/">Google Books</a>: Lots of books, resizing the window results in words re-order/pages renumbering to fit the new size, change font sizes.</li>
<li><a href="https://read.amazon.com/">Kindle Cloud Reader</a>: from Amazon, also resizing window results in words re-order, can take notes, change fonts. It's just like a Kindle device in your browser!</a></li>
<li><a href="http://ibisreader.com/">Ibis Reader</a>: Didn't try it yet, but it seems very good from first look at screenshots</li>

Now, I've looked everywhere to find opensource tools to help with this job, for the basic functionalities at least (resizing and re-order, change fonts, table of content), but I didn't get anything useful even on github. The only useful one I found is <a href="http://code.google.com/p/20thingsilearned/">20thingsilearned</a> but it's built upon App Engine!

So my question is, is there any real stuff that I can build upon freely & in opensource fashion before I begin working on similar one myself?
