PubML is a full-featured publishing system that exports to both traditional eBook format (ePub) and a unique <PubML>™ format that works in any web browser (PubML is short for "Publishing with HTML"). The <PubML>™ Publishing tools were designed to be flexible and easy to use, but creating a quality eBook—especially one that contains links to photos, videos, and other outside media—involves numerous aesthetic decisions and technical steps. This help file was created to assist you with how to design your own eBook, but it also offers design guidance. For example, most writers are unfamilar with the subtleties of book typography; the road to hell is often paved with bad font choices. Links are provided to relevant articles on TheWorldsGreatestBook.com and video tutorials are included as needed. Important publishing vocabulary words are highlighted in red.
