How to self-publish an ebook | Fully Equipped - CNET Reviews: This is Amazon's e-book publishing platform and if you think you're going to sell a lot of e-books, you should figure out a way to upload your file (book) directly to KDP and avoid using any sort of middleman or e-book "aggregator" that takes a cut of the profits. If you're a true DIY person, you can create your own cover (though if you're not a professional designer, it's better to hire a pro) and format your e-book from a Word file using free software tools such as Mobipocket eBook Creator or Calibre. Mobipocket Creator allows you to create an e-book with a table of contents and convert it into Amazon's proprietary e-book format, AZW (MOBI, the file output by the program, is the same as AZW). You can start with a Word file, which then gets converted to HTML, then MOBI. (Check out the Mobipocket eBook Creator guide at the company's Web site).
