This is a very interesting piece on the transformations that had took place in the publishing market. Still the authors fail to mention even once the success of Publons that was acquired by Clarivate Analytics in June 1 of 2017 https://www.nature.com/news/web-of-science-owner-buys-up-booming-peer-review-platform-1.22094 when the platform had around 150.000 reviewers and around 800.000 reviews. Just 8 months after that date Publons have now almost 270.000 reviewers and more than 1.500.000 confirmed reviews. Being forecast that by the end of January of 2019 the number of reviewers on that platform may reach almost half a million. This will not only allow to tackle of problem of fake peer review but will also in future help to take away peer review from Publishers. When that finally get to be a reality then authors will not need to endure several peer review phases in different journals. Also the paper mention the fact that Elsevier acquired Mendeley, SSRN in 2016 and Plum Analytics a leading provider of altmetrics in early 2017 but they offer no justification for that. The recent text below from Richard Smith former Editor of BMJ (former British Medical journal) gives some clues on the motivation of Elsevier: "…the leaders of Elsevier have now decided that the epoch of journals will soon be over. They are not buying or starting journals. They now describe the company as a “global information analytics business that helps institutions and professionals progress science, advance healthcare, and improve performance.” They are a “big data company.” Instead of buying journals they now buy software that scientists will need... …The company recognises that science publishing will become a service that scientists will largely run themselves. In a sense, it always has been with scientists producing the science, editing the journals, peer reviewing the studies, and then reading the journals. But innovations like F1000Research and Wellcome Open Research have shown how the services can be provided much more cheaply—in part by dispensing with editors who make (often arbitrary and wrong) decisions on what’s important and what is not… …The company thinks that there will be one company supplying publishing services to scientists—just as there is one Amazon, one Google, and one Facebook; and Elsevier aims to be that company. But how can it make big profits from providing a cheap service? The answer lies in big data…Elsevier will come to know more about the world’s scientists—their needs, demands, aspirations, weaknesses, and buying patterns—than any other organisation." http://blogs.bmj.com/bmj/2018/01/10/richard-smith-a-big-brother-future-for-science-publishing/
