If you don’t know how to publish your story or novel as an e-book on Barnes and Noble, NEHW Co-Chair Tracy L. Carbone has written a blog entry on her website explaining how she did it. You can read it here. At the moment, this is the first entry on her site so it is at the top of the page.
She also has another entry, “How to Waste Money on Marketing,” which you will have to scroll down the page to find. It’s worth the time to search for it. It will save you money.
