Caught this presentation link on Twitter from Liza Daly at Three Press Consulting. Liza gave a presentation recently on designing eBooks for 2 epub reading engines rather than designing eBooks for 99 different readers (and counting). What is a reading engine you ask? According to slide #7, “A reading engine is the part of the ereading software that actually places text on the screen. It’s the most basic, primitive, component of any ereader.” Her presentation focuses on designing eBooks for 2/3 of the popular epub reading engines – Adobe Reader Mobile SDK (RMSDK) and WebKit. Liza says that thinking about reading engines can really simplify issues around eBook design.
Liza has also designed her own ereader – the Ibis Reader. With Ibis, you can read epub books on a computer or mobile device and your content is stored online, so you can access it anytime.
