How to follow the Top Ebooks Provider Companies

First decide whether you are a publisher or just a reader or digital knowledge consumer?

You can sell your self-published books through the Blurb Book Store, Amazon, or stores such as Barnes & Noble via the Ingram catalogue. IngramSpark helps you publish both printed books (hardbacks and paperbacks) and e-books.
IngramSpark charges $49 for the upload of the print book, and there is no extra fee if you publish as an ebook, too. You can then publish the book on the platforms site, Lulus, but also have it formatted to read it on other ebook readers and apps too.
BookBaby is an ebook aggregator service, where you can publish your e-book and they will then disseminate it across a range of different sales platforms for you, including Kindle Select. So, publishing your ebook through Amazon Books and Kindle is the obvious one on the top of that list.

Amazon is the largest publisher of ebooks on the planet, and 300 million potential readers are waiting in the wings just waiting to read a new book. Amazon is a leading retailer of ebooks, with over 6 million of its Amazon Kindle ebooks available from Amazon. As one of the largest sources for ebooks on the web, Amazon has a significant self-publishing division, Kindle Direct Publishing. Amazons Kindle Direct Publishing[KDP] is a self-publishing platform for authors to publish their books in print and eBook form.

Smashwords allows you to publish your eBooks on various sources, including Smashwords store, Google Books, Barnes & Noble, Kobo, and Scribd.
