E-book Publishing Formats

E-book publishing is a great way to distribute your book. It’s usually costs much less than traditional publishing and gives you a better royalty rate. It also is an environmentally-friendly alternative to traditional publishing. E-books are published in a variety of formats so they are compatible with the different reading devices on the market today. The different e-book publishing formats make it possible for e-books to be read on a computer, e-book readers such as the Kindle, and even some smartphones. Here are just a few of the most common e-book publishing formats available to iUniverse authors through our e-book publishing:
