I published eight things in 2014: two novels, and six novellas. The novels were through a publisher, and one is already off the market–I reclaimed the rights–and will be re-released in 2015. The six novellas were self-published. There is no way I would have been able to produce that many titles through a publisher in a single year. Publishers have multiple writers on their calendars and an interest in not promoting too many things at one time. They also have editorial deadlines and cover art deadlines and contractual deadlines and reviewer deadlines. If I finished a 20,000 word novella right now, if I was very, very lucky it would be in the hands of readers in six or eight months. Contrast that with what I actually did in eight months, which was write and publish six stories.
