I only put links here that I think are valuable to authors, legitimate and that I have used. That’s why I’m only starting with a few. Note: some of these I get a small payment for if you click on the link – the logo is the link – most I do not.
BooksGoSocial is a site that helps authors with different aspects of publishing but mainly marketing, and don’t all authors need help with marketing! If you click on the image, it will take you to their list of online classes.
IngramSpark is the self-publishing branch of Lightning Source (Note: this is not as simple and inexpensive way to publish compared to kdp.amazon ie., you might want to hire someone to do your interior pdf file to meet their specs, and they charge a setup fee, but it has more distribution options and less quality issues than amazon.). You get to choose the % cost to your for selling to the various distribution channels. They recommend 55%, which is that industry standard, but you can choose a different percentage if you so choose.
They are easier to use than IngramSpark but if your book isn’t purchased through them, the cost to you for their wider distribution channels is 60%, and your book might or might not be available to libraries.
For those do-it-yourselfers out there, here is a ebook formatting program that I recommend. It is user friendly with a good Help section and an even better online chat group – which is mainly Julian, the creator of Jutoh, answering questions 🙂
