I&#x27;d also be interested in this answer. What I have done is email researchers directly asking for a PDF and they have been happy to give me one. Often some of the authors have their own site where they add links to their own papers.<p>Now, is this because these authors are exercising their own right to distribute their work, and many other authors don&#x27;t want to expend that effort? The copyrights don&#x27;t change after all, so collating these and redistributing could also be the same as sci hub.
