Predatory publishers are those publishing counterfeit journals to exploit the author-pays open access model. They set websites that closely resemble those of legitimate online publishers, and publish journals of very low quality. Only after the paper is accepted and published, and copyright assigned, the authors are invoiced for the fees. The research community should use social networks such as Connotea and Mendeley to identify and share information on those publishers.
