Online booksellers are rapidly becoming online publishers. Sell your short fiction or nonfiction to the newest markets. Anyone who publishes your compiled short stories, novels, or nonfiction is looking for more opportunities to market your work. If you have published your stories or nonfiction with a mainstream or print-on-demand publisher, that firm cooperates with online booksellers. They probably want to leverage serial rights opportunities with your short stories, articles, or nonfiction excerpts from your books. After publication, you need to drive people to online booksellers' Web sites and your own to create visibility. The revolution is in virtual book tours and online marketing with booksellers. Another hidden market is short story publishing rights' auctions online to create visibility. You sell your writing as you'd sell a product at one of the online auctions. Long before finding any publisher or after the "face-out shelf life" of your book is over, sell or pre-sell your creations online. Offer short stories or articles to the public for a small fee to download. The music and movie industry do it. So can you. Online booksellers already are famous for a targeted community of readers that buy online. That's only one hint of hidden markets for authors that want to be well-paid for short stories or brief nonfiction. Here's how to write, customize, and market precisely what these merchants want. Here's how to pose the least financial risk to them.
