Sigil. calibre (yes, with a lower-case first letter.) There’s even one called Hamster.
If you’ve ever searched for a tool to convert your manuscript to an ebook, you’ve come perilously close to drowning in geekness.
Stop. Step back. Put down the chainsaw; you don’t need one to make a toothpick. Especially if you already have a box of toothpicks.
Everything I say in the rest of this post will have exceptions. I’ll mention a few at the end, but if your manuscript doesn’t fall into the exceptions, don’t go to exceptional lengths to get the job done.
For some reason, one of the questions I’m asked most frequently is “Should I publish an ebook, or have it printed?”
Perhaps when I waded into self-publishing I was too ignorant to realize I needed to choose.
Turns out I was right: you don’t have to choose. In fact, doing both simultaneously is efficient and sensible. All the work of preparing your manuscript is the same, whether you’re preparing a digital or printed book. Writing, editing, proofreading: the words will be the same in any version of your book.
