Roy and I have been deliberating over this for some years. There are some substantial costs involved to ensure correct copyright protection. Digital?editions really require a different layout to support small devices which means double the production effort. And having a digital edition is likely to reduce, rather than supplement,?the paper distribution to the point it becomes unviable. And we have had many people stating they prefer the paper as evidenced here.
@Brian - we do have a searchable digital index here:?
