a post by her that gives some specific tips for designing an ebook. This is nice to have because Wright knows a lot about print book design, and she has noted those things that need to be different in an ebook.
For example, in a print book, with a (potentially) larger page, the design can rely on white space more than in an ebook where the screen is often very limited in size. The scene break style in a print book might include several lines of white space, but only one or two lines in en ebook. That means you need something—a rule or a different font size—to distinguish the new scene from the old.
It isn't enough to produce an ebook with no typos. If you want your book to be readable, you have make sure it's easy to navigate as well as an engrossing read.
p.s. Smashwords seems to be stable for now, but they haven't had an update of other retailer info in quite a while. Apple, Diesel, and Kobo are still showing sales data only through December 31, and Sony though January 28. Barnes & Noble is still in the lead with data from February 2.
