“The publishing giant Elsevier has acquired the Social Science Research Network, an online open-access repository for research. Elsevier said in the announcement that it plans to develop SSRN alongside Mendeley, the company’s own academic social network. Neither SSRN’s user policies nor its leadership will change, Elsevier said. It will still be free for users to submit their papers and download others. Elsevier did not disclose how much it paid to acquire SSRN.”
