As I travel down the self-publishing road, I will collect some of the most useful resources below. If you have anything to add, please let me know.


  • Sigil An open-source app for creating/editing ePub files. I love this application! ┬áHere is the documentation.┬áThere is also great documentation on ePub conversion.


    • Threepress Consulting Blog A nice resource on ePub development. You can also validate your ePub file on their site, though I’ve had mixed results so far. You can also download the ePub validation software yourself and run it on your computer. But you have to be comfortable using the command line; if you don’t know what I’m talking about, stick with the blog above. But note that the errors you may get by the validation engine are generally very cryptic. More digging will usually be required to know what exactly is wrong. I’ve been there.
