Blurb, a creative book publishing service, today announced that its new BookSmart beta release is available for download from its Web site. Version 1.3 enables Blurb customers to use any font installed on their computers, plus offers a new vertical book option specifically designed to showcase business books and blogs, full bleed dust jackets, and four new ready-to-customize cookbook themes. BookSmart 1.3 runs on a Mac or PC and is free to try; users pay only when they publish. Each book is then printed on demand, in any quantity — whether that’s one for a gift, a couple dozen for family members, or several thousand to reach a wide audience.
