(From the modal link on the top-right)<p>With liveBook:<p>- The books are free<p>- Full-text search for books<p>- Browser-based<p>- Audio readings with an arrow on the left / text highlighting to keep up with the book<p>- On the right-sidebar of a book, it offers to buy the book in PDF/ePub/kindle form.<p>This is similar to Leanpub's online reading option (<a href="https://leanpub.com" rel="nofollow">https://leanpub.com</a>).<p>I used it to write and publish <i>The Tao of tmux</i> and made it available online free (<a href="https://leanpub.com/the-tao-of-tmux/read" rel="nofollow">https://leanpub.com/the-tao-of-tmux/read</a>). Like liveBook, users can opt to buy the book in DRM-free epub/pdf/mobi and have it sent to their Kindle.<p>What liveLeak seems to have that Leanpub doesn't is audio readings.<p>Another cool trick: on the left side of a liveBook (e.g. <a href="https://livebook.manning.com/#!/book/grokking-algorithms/chapter-1/1" rel="nofollow">https://livebook.manning.com/#!/book/grokking-algorithms/cha...</a>) mouse-over on the left side of a section of the book and you can start narration at that point.
