Recently, I downloaded the following books because they were priced at one cent. Turns out, they have good information and are worth your time. Because we all develop our own work patterns, I don’t do everything like the author, but I picked up some excellent information and tips.
Aaron Shepard is a self-published author and blogger (Aaron Shepard’s Self-Publishing Page) with the experience of over 30 books behind him, and a curious, intelligent mind that led him to do extensive experimentation with formatting. Instead of reinventing the wheel, I recommend reading his books to learn from his research.
