It makes sense to download this book and see what it has to say, but don't rely on it for anything other than a trip through the uploading process once you've pulled everything together.
Of rather more practical use is [[How to Publish your own eBook by Nik Rawlinson]], which does give explanations and advice. We were also quietly impressed by [[The Book Publishers Toolkit: 10 Practical Pointers for Independent and Self Publishers Vol. 1 by IBPA Contributors|The Book Publishers Toolkit: 10 Practical Pointers for Independent and Self Publishers]]. If you're looking for a literary agent, you might find [[3 Things You Should Know About Literary Agents|this]] helpful.
