In our madcap rush to digitize the book we’ve been all too willing to attempt both to recreate the physical book experience in the digital realm and to just as quickly discard any feature of physical books that proved too challenging to duplicate online. Part of the problem was inherent in the original E Ink-enabled Kindle. Amazon managed to create a lowest common denominator digital publishing standard. Having done so there’s a real inertia around improved book-like features. Both EPUB 3 and Amazon’s Kindle KF 8 define a robust set of features. And so far the support for these file formats is spotty at best (the BISG [Book Industry Study Group] offers a very useful grid which notes the details of advanced formatting on digital platforms).
