Going Amazon? Then you need Kindle eBooks.
What Do I Need To Publish At Amazon?
The short answer is, you need a MOBI file (the file format used by Amazon for eBooks) and a cover, for your "catalog" image (the image that Amazon shows on your sales page, and the thumbnails). That's it!
How Do I Create My MOBI File?
Depending on where you go, and how "tecchie" you are, some folks will tell you that all you need is a Word file. Use the Word file, use a cover that you make with Amazon's "Kindle Cover Creator," which you access and use from within their Bookshelf, and off you go! Free! Badda-bing!
But here's the thing: you know, and we know, that we've all seen those efforts. Sure, some are fine. But how many have you seen, as you go around Amazon and B&N (and particularly Smashwords) that aren't "fine?" In fact, they are as far from Fine as humany possible.
Don't Be Fooled...
A Kindle book isn't a word-processing file. For that matter, they're not even editable. A Kindle book is actually a binary database file, built from its HTML source. In its guts, a Kindle book is HTML. To make a book look great, and render perfectly, you need a good command of not only HTML--yes, the same HTML that makes websites work--but what's called "CSS," as well--the secrets of styling. The secrets of commanding a book to work correctly, whether it's being viewed on an Amazon Fire tablet, a Paperwhite e-ink reader, or a smartphone Kindle reading app.
What many new-to-Amazon authors don't know is that if your book is poorly formatted, contains typos, or other mistakes, Amazon will send you a KQN--a Kindle Quality Notice. This requires you to fix your book and re-upload it. If the problem is adequately persistent, they'll remove your book from sale themselves, and force you to fix it. You can avoid this embarrassing and costly issue by hiring a quality formatting company in the first place.
