In this jungle of self-publishing, writing is only half the battle. The next thing is to decide your format.
Traditional books are physical books—paperback or hardback.
E-books are just that—electronic books. There is a reason Amazon has made so much money with Kindle! I mean, as a bibliophile? I love being able to take my entire library with me ALL THE TIME.
What I want you to remember both have their advantages, and disadvantages. But know that you are in control. It is important to research your options, as well as what your work requires.
Some things to consider while deciding which set up is right for you and your story:
What is the genre?
Is this a collaboration with another writer or an anthology?
What is the publishing date?
All these things matter when making the transition from messy idea to final draft. The work has to consider not just the ease of formatting—but the ease that is translated to the reader.
Go forth and write!
