Both customers who have previous made books using Blurb's digital tools, and new clients who have always wanted to create a physical photo-book as a keepsake now also have the option of turning their works into full-fledged e-books, from the same file as was used to create the physical book. New authors have the option of choosing either format, and the resulting e-books work with the iBooks application for iOS, including two-page spreads and pinch/zoom capabilities.
