ISBNs help books get discovered!

Purchasing an ISBN is a big step toward ensuring your book’s commercial success. An ISBN can help readers find and purchase your book because it identifies the book’s specific format, edition, and publisher. Also, the ISBN:

  • links to essential information about your book
  • enables more efficient marketing and distribution
  • is required by most retailers
  • is the global standard for book identification
