"As online journal access becomes the norm, the expectation has been that e-books will follow suit. But the reality is patchy provision of e-books as publishers withhold core titles, especially textbooks, for fear of catastrophic print revenue losses.

Publishers are still experimenting with e-books, aggregators are coming under pressure from publishers and users on price, sales models and licensing structures, while information professionals and users are demanding more core titles and better prices."

I think the big problem is the belief that anything digital should cost more than print when the opposite should be true.
