• In thinking about what roles libraries will play when all books are e-books, I keep coming back to a conclusion that sounds odd at first: the prospective role of libraries will be entwined with that of piracy in the e-book ecosystem. While there are fundamental differences between e-book libraries and e-book pirates, there are important similarities.

We must recognize that "free and easy" access to digital content is not only not going to happen, it is the enemy of universal access.
