I'll bite: is there anything novel presented over these book-like pages, or it's just an introductory text? The lack of navigation syncing up with the page I'm on makes it hard to tell if I'm 10% or 90% through the content. If there was a printer-friendly view, it would be much easier to evaluate whether this content is relevant to me or not.
