The International Digital Publishing Forum (IDPF) develops, publishes and maintains open standards such as EPUB, for digital publications and promotes the world-wide adoption of these specifications. As quoted in their website, "the EPUB® specification is a distribution and interchange format standard for digital publications and documents. EPUB defines a means of representing, packaging and encoding structured and semantically enhanced Web content — including HTML5, CSS, SVG, images, and other resources — for distribution in a single-file format". Although, EPUB 2 is still widely used by the industry, the latest major release of EPUB is the third version EPUB 3.
Several EPUB software are out there, mostly for free, by which you can create, edit and read electronic books:

With global outreach and marketing features like KDP Select, KDP could be the right option for you.

There are two components to Google Books Partner Program:
(1) Selling digital editions of your book where you earn royalty (52% of the list price). Google has the ability to accept a file in PDF or ePub format, or a physical copy. If you send them a hard copy, Google will use proprietary scanning technology to prepare your book for display on Google Books.
(2) the Preview Program is a free marketing program that enables publishers and authors to promote their books online, through Google Books by submitting a digital or physical copy of your book so it can be previewed online.When a reader finds the book on Google Books, they'll see a limited preview of your book, as well as a series of links to purchase your title at major online retailers. You can also add a custom link to the book's listing on your own website.
Since it is a tedious job for authors to sign up for each online retailers and submit an e-book for publishing, authors can use third-party companies to get this done for a certain fee. These companies known as Aggregators will publish your e-book to major online retailers on your behalf. There are several of them, but the ones I know about are: Smashwords, Bookbaby and PigeonLab. Visit their websites and see which one fits your needs.
Getting an ISBN
An ISBN is a 10- or 13-digit number that uniquely identifies published books worldwide. ISBN stands for International Standard Book Number. You do NOT need an ISBN to sell your e-book on any of the online retailers mentioned above. However, if you choose to have ISBN for your books, you can purchase it from Bowker in the US, and from an International ISBN Agency outside US.
Note that you need separate ISBNs for your e-book and the printed copy of the e-book. In fact, if you plan to publish a book in hard cover, soft cover, PDF, with or without illustrations, you will a separate ISBN for each variation.
Selling your e-book from your own website
Unless you have given exclusive selling rights to any of the on-line retailers, you should be able to sell your e-book from your own website. Companies like My Commerce and Kagi provide such services where authors even with minimal IT knowledge can implement shopping cart and payment capabilities to their websites. It is worth looking at selling your own e-book as it allows you to keep 100% of the royalty (minus the small service fee charged by these e-commerce companies).
Self-publishing industry is rapidly changing and it is important to keep yourself abreast with the latest and the greatest of what's going on. I recommend self-publishing authors to frequently visit the websites of on-line retailers and Aggregators. You can get updates about EPUB software by signing up for newsletters from the specific websites. Additionally, you may find the following links very useful:
