Apply for an International Standard Book Number (ISBN). This number will be used to identify your book in marketing, distribution and sales and will help you to ensure the content remains your own. You can apply online, in the U.S. or Canada, at SelfPublishing.com or Government of Canada Publications.
Decide on a format. One option is traditional print, which might be a run of a specified number of copies or print on demand. Alternatively, you could publish in a digital format, such as an ebook or audio book. Conventional print is still more accepted by readers, though digital copies are definitely making headway. On the other hand, technically savvy writers can publish an ebook with a lot less effort and on a tighter budget. Selling digital copies might help them develop a following for future publications. Each choice has its perks and drawbacks, so authors should consider their goals when making this decision.
Determine how much of the publishing you will do yourself. Will you design your own cover? Will you handle the printing? Will you upload content to the web? Will you promote and distribute your book independently? Innovo Publishing (U.S.) and Word Alive Press (Canada) are Christian publishers that understand the pros and cons of do-it-yourself publishing and offer a variety of options and packages that will fit your needs, schedule and technical abilities.
Promote your book relentlessly! Getting your book out there is the easy part. Without the backing of a well-known publisher, you will be responsible for the marketing and promotion of your material. Be prepared to visit Christian and mainstream bookstores, hold signing parties, cold-call churches or faith-based schools, market at related Christian conferences and promote your work on blogs and social networking sites.
Keep writing. If you achieve all of your goals with this book, you'll be the envy of every writer in the field. On the other hand, maybe your sales will be limited, and you will find yourself a little disillusioned. No matter what, use this opportunity as a learning experience and enjoy the process.
