.epub eBooks Tutorial - Part 1 - Formatting Your Source Content

"Why am I talking about source documents? Because the end result--your book-- is only going to look as good as the code that goes into it. When I first created the ePub tutorial, I skimmed over creating the source document and just talked about the ePub format. After making and editing several ePubs for my own use, I have seen more and more that the HTML you start with determine how nice the final book looks. "
