- Go over the papers in the reading materials folder and check for each one: - is it open access? - is it a preprint (no layout of a proper journal/conference, or it says "preprint" - if the answer to any of these questions is "yes": leave the paper in the repo. - if both questions are answered with a "no" or "unsure", remove it from the repo (it's listed in the reading list with a link anyway)
