How do I use the ebook functions epub_book and kindlegen() for existing bookdown documents?

Epictetus wrote nothing; and all that we have under his name was written by an affectionate pupil, Arrian, afterwards the historian of Alexander the Great, who, as he tells us, took down in writing the philosopher’s discourses

“But wait—you could still re­lease your book in EPUB [or some other open e-book for­mat].” If you can show me an e-book for­mat that gives me the same con­trol over ty­pog­ra­phy and lay­out that I can get in a web browser, I’ll con­sider it. As far as I know, it doesn’t ex­ist. (If I’m wrong, please con­tact me.)Thus my op­tion here is to use EPUB to make a ty­po­graph­i­cally ugly book about ty­pog­ra­phy. Do I want to make that? No. Do you really want to read it? I doubt it. A key point in why does ty­pog­ra­phy mat­ter is that ty­pog­ra­phy in­flu­ences reader at­ten­tion. If you like this book, in part it’s be­cause the ty­pog­ra­phy is help­ing you en­joy it. If I re­move the ty­pog­ra­phy, I can al­ready fore­see the results.

if cross-format identifiers like DOIs are used, annotations made in one format (eg, EPUB) can be seen in the same document published in other formats (eg, HTML, PDF) and in other locations.

Think of the educational potential.

The EDUPUB Initiative VitalSource regularly collaborates with independent consultants and industry experts including the National Federation of the Blind (NFB), American Foundation for the Blind (AFB), Tech For All, JISC, Alternative Media Access Center (AMAC), and others. With the help of these experts, VitalSource strives to ensure its platform conforms to applicable accessibility standards including Section 508 of the Rehabilitation Act and the Accessibility Guidelines established by the Worldwide Web Consortium known as WCAG 2.0. The state of the platform's conformance with Section 508 at any point in time is made available through publication of Voluntary Product Accessibility Templates (VPATs).  VitalSource continues to support industry standards for accessibility by conducting conformance testing on all Bookshelf platforms – offline on Windows and Macs; online on Windows and Macs using standard browsers (e.g., Internet Explorer, Mozilla Firefox, Safari); and on mobile devices for iOS and Android. All Bookshelf platforms are evaluated using industry-leading screen reading programs available for the platform including JAWS and NVDA for Windows, VoiceOver for Mac and iOS, and TalkBack for Android. To ensure a comprehensive reading experience, all Bookshelf platforms have been evaluated using EPUB® and enhanced PDF books.

The W3C Annotation Working Group has a joint deliverable with the W3C Web Application Working Group called “Robust Anchoring”. This deliverable will provide a general framework for anchoring; and, although defined within the framework of annotations, the specification can also be used for other fragment identification use cases. Similarly, the W3C Media Fragments specification [media-frags] may prove useful to address some of the use cases. Finally, the Streamable Package Format draft, mentioned above, also includes a fragment identification mechanism. Would that package format be adopted for EPUB+WEB, that fragment identification may also come to the fore as an important mechanism to consider.
