I just read the following article at Wired that supposedly tells you how to create an ebook.
http://howto.wired.com/wiki/Roll_You...tories+2%29%29
One thing they got right--they do recommend using epub. It was obvious even to Wired that everyone but Amazon supports it, as they state in the article.
As for their recommended tools and workflow, if it wasn't so sad, I'd laugh. Using Microsoft Word, start by creating a PDF. Then feed that PDF into Calibre to generate an epub. If you have to use MS Word, at least save to HTML and then use Tidy to strip out all the junk that MS puts in. Why anyone would think that using a PDF as an intermediate step in ebook creation is a good idea, I simply cannot fathom.
I can think of several alternate workflows that make much more sense. And as for software, there are several other programs (free and paid) that would do a better job of creating an epub.
I not only blame Wired for not reviewing this article before publishing it, but the author needs to get some real world experience and along the way, buy a clue.
