Re: Accessibility of EPUB vs PDF

Hi Ajay,

All valid points, but large publishers have different budgets and resources
than the average Joe or Jane in business or an organization. In my
experience and view, if there is no easy to use and stable plug in for Word
that creates EPUB 3 and above with a 'save as', EPUB will never gain major
market traction. At least InDesign is now, in my view, able to produce
fairly good EPUBs (if the author produces an accessible InDesign doc), and
that is a good start...but it has a long way to go.

Cheers

Lisa
