Two large scientific publishers, Elsevier and the American Chemical Society, have filed a lawsuit against the scholarly social network ResearchGate to prevent copyrighted material appearing on its site. The publishers are two of five that on 5 October announced they had formed a coalition to start ordering ResearchGate to take down from its site papers that breach copyright. Up to 7 million papers may be affected, the coalition statement said. ResearchGate, based in Berlin, declined to comment on the lawsuit, which was filed in a German court.

Note: Elsevier is the publisher of the Journal of Biomechanics
