The Scribd digital library has entered into a deal that will add HarperCollins Publishers’ back list e-books to Scribd’s subscription service. This arrangement with a major publishing house is a big move for Scribd, which already offers books from smaller publishers including Workman and the Indiana University Press. Scribd plans to also sell e-books from the full HarperCollins catalog, including new titles. Scribd has a customer base of 80 million users per month. (Tech Crunch)(The New York Times)
