Philadephia paper on ebooks
So far, this article by the Philadephia Inquirer's editorial board is the best I've seen on the subject. In particular, I liked this: "Librarians rightly argue that they are spending dwindling public resources on e-books, so they should get a break. Part of their job is to help build a literate society, which is essential to a strong democracy. They also make a strong case that libraries generate business for publishers."
