One reason why the project management skills of the editor are more important today than ever is that publishing, particularly in education and academic fields, is not only about books. Almost none of the projects we work on today is 'just' a book. The most straightforward publication will have a print and an e-book version, many books have linked online resources, and an increasing number of projects are multi-component, with interrelated print materials alongside digital products containing hundreds of resources in different formats, from Word files to video. Then there is the marketing material—the samples for social media, the database that feeds information to Amazon, the advance chapter and cover.
