Briefly Noted | Go To Hellman: How Apple May Inadvertently Boost eBook Linking
Since EPUB3 is based on HTML5, all the outbound linking that you would expect from a web page is already built into EPUB3 (as well as earlier versions of EPUB). Ebook reader apps available on iOS and Android use the “Webkit” webpage renderer for ebooks in EPUB. (Kindle devices use Webkit to render web pages and WebKit is used by Amazon to render Kindle ebooks (in mobi format) on hardware other than their own.) So it’s clear to me, at least, that even if ebook reader apps can’t have “Kindle Store” buttons, the apps will be able to present “Kindle Store” links inside the ebook content. I’ll bet you anything that Amazon is loading up ebook content with Kindle Store links: “If you like this book, perhaps you’d like this one”. They’ll even have specialized shop-books containing Kindle store links available for free. Ditto the others.
