The new software from Amazon that allows publication of an e-book is called Kindle Create. I've been exploring it with a view to publishing my next book, which is due in a few days. I'd love to give an official date of publication, but sod's law says I won't stick to it, so I'll just say it is very close.
At first glance the software seems beautfully simple, and in many ways, it is.
There is a choice of four themes to suit different genres - Classic, Amour, etc. They aren't exactly startling, but it means the software will modify the entire text for you to that style. It will seek out paragraphs, breaks, headings etc and deal with them for you, according to the style you've chosen. You can be certain they will all be consistent.
The software will do the Table of Contents for you, too.
If you have any links, the software will hold them but once you try to modify them they vanish.
My needs are simple as I have no illustrations, graphics or lists to incorporate. It is a plain novel, and the software seems to suit me well so far. One draw back I've noted is that though you can edit the text in Kindle Create, it - obviously when you think about it - doesn't make the change in your original Word document, so you could end up with no final copy of your ms.
If I had made all my editing changes on the Word document, I would have been further on by now. I had about three goes at editing on Kindle Create before the penny fnally dropped. Now I'm back to doing a final, final, final edit on Word, so in a sense I've wasted all the time I spent each time making the style changes. Next time I'll know better!
