Also met with HBj. Although now a hand-held device needn't be web connected, it could be. Keep layout unclouded, use icons, animations. Web Accessibility Initiative needs to address this issue, with authors and with publishers. We have missed communicating the accessibility message for existing authors and publishers.
Publishers are in the business of obsoleting the current editions of books.
Accessibility may be a good reason. Get list of publishers, based on ISBNs. Should contact them about this issue. JB read abstracts. Students can't access it.
