Self-published books earn little but help publishers spot trends
Some authors publish their books online without using a traditional publisher; they are known as self-publishers.
Their books bring in about 4 billion francs worldwide, or 2 to 5 percent of the global book market.
Although the business is small, self-published writers can help reveal what readers are interested in.
Established publishers watch these trends and may sign authors writing in promising areas.
Erika Mitchell, who writes as E.L. James, first self-published “Fifty Shades of Grey” before signing with a large publisher.
The series has since sold 125 million copies, but very few self-published authors achieve comparable success, and many cannot live on their book earnings.
Some companies charge authors thousands of francs to help them self-publish, while an authors’ association offers free support.
Self-published books are easy to release online but generate little income for most authors.
Worldwide, self-published books bring in about 4 billion Swiss francs, or 2 to 5 percent of the book market’s total revenue.
Self-publishers can help established publishers spot reading trends and identify authors to sign.
E.L. James first published Fifty Shades of Grey herself before a major publisher signed her.
The self-publishing sector also includes services that charge authors thousands of Swiss francs, and some providers exploit them.
