SAGE Open is an open access journal launched by SAGE Publications in 2011 to serve the social sciences and humanities. It uses the PLOS One model of peer review. Since its launch, it has received over 2,500 submissions from 62 countries. While challenges include marketing open access to the humanities and social sciences, addressing perceptions of open access publishing, and pricing, SAGE plans to launch 40 additional open access journals in 2014 to further their involvement in open access scholarly communication.
