Last week Macmillan purchased Pronoun, an eBook creation, distribution, and marketing service for independent authors. (See announcement.) Along with Pronoun, Macmillan purchased an innovative entourage that includes Booklr, a data analysis service for eBook sales, and Byliner, which publishes “urgent, necessary journalism for the present day” along with short fiction and serials. But I think that what Macmillan really bought was innovation, which in the generally stodgy world of traditional publishing is rare and admirable. And that innovation is data-centric.
