An ISBN allows retailers, libraries, and others in the supply chain to more easily find and order your book. It also provides a professional appearance and can make your book appear more credible to potential readers. We recommend that you buy ISBNs for your book before you begin the self-publishing process. This will give you one less thing to worry about as you move forward. freeisbn.com/
