The Christian book market has been shrinking over the years, explains author, editor, and owner of The Christian Communicator, Susan Titus Osborn. There has been a significant decrease in Christian booksellers, as well as publishers – Osborn says that the Christian Writers Market Guide now lists 200 traditional Christian book publishers, half of what was listed 10 years ago. This has caused many Christian writers to turn to self-publishing. When taking this route, Osborn urges writers to market themselves online and through events. She also advises self-published writers to get their work professionally edited, to make the book polished and appealing.
