This is something I’ve mentioned before, but it can make the difference between a professionally formatted work and one that screams, “Amateur!” Have you ever noticed that formatting for fiction is different than nonfiction? Fiction typically has indented paragraphs, nonfiction has block paragraphs. If you don’t believe me, go into a bookstore (or your own bookshelf) some time to see for yourself.
I don’t know why this convention evolved but I’m sure there’s a reason. I suspect that perhaps block paragraphs make it easier for the reader to grasp nonfiction concepts in small bites whereas a novel should flow more easily.
I remember the first time I sat down to format a book I realized I’d never paid much attention to such things. When you become an Indie Author it becomes your business to know. Other details, such as headers, footers, pagination, chapter headings, and so forth are more negotiable.
The next time you read, pay attention to the formatting. It can provide various do’s and don’t’s for your own.
