In 2001, Steve Lawrence published a hugely influential study which showed that OA conference papers in computer science were cited more than twice as often as papers that were not accessible online. But Lawrence’s paper is twenty years old and his study was limited to one kind of paper in a single discipline. Today, we know far more than in 2001. So the Policy Labs team ran a small-scale study to find out what scholars have found out.’
