I am so happy to announce that the EPUB version of my book about EPUB, titled EPUB Straight to the Point: Creating ebooks for the Apple iPad and other ereaders is available right now. I've created a new section of my website that gives a synopsis, an excerpt to show you what it looks like, shows the final table of contents, and lets you browse the complete index (which is live in the EPUB version), as well as buy the EPUB version of the book right away (facilitated by Kagi).
I will only be selling the electronic version from my website. If you'd like to wait for the print edition—which should be in bookstores by the end of the month, you can preorder the book from Amazon, Barnes & Noble, or my publisher, Peachpit Press.
This is the first time I've ever sold my own books from my own website, and I'm both excited and nervous. Please let me know if you have any trouble with the Kagi site, or with my end of it, and if there's anything I can do to make the process easier.
Note that the EPUB version of my book has no DRM. You can read it in any ereader that supports EPUB.
