Two New Services Aim to Improve Access to Scholarly PDFs

"As I noted earlier in this article, technology has turned the library world on its head. Instead of a place that carefully preserves paper materials for the ages, the library is a hub for disseminating online books and articles to credentialed patrons. By the time I retired, the online catalog in our library contained two ebooks for every paper title. Sites such as Unpaywall and Kopernio herald the news that the information revolution is far from over."
