In this study we have sketched the development of scientific communication and the scientific journal over the centuries, up to the e-journals of our times (chapter 2), and analyzed in depth the use made of digital means by the authors of peer-reviewed articles. To go beyond mere description, we must now address the question
scientific communication has developed in the way it has. More specifically, we are interested in the way technology has impacted on communication and why specific solutions have been adopted above others. Understanding these issues, i.e. employing explanatory theories of change, will allow us to put into perspective the impact (and claims made about the impact) of digital information and communication technologies on the scientific article now and in the future.
