From a SocArXiv Blog Post:
SocArXiv, open archive of the social sciences, has launched an initial round of fundraising to support outreach, development, and administration. To kick off this drive, we are delighted to announce that the libraries at the Massachusetts Institute of Technology and the University of California, Los Angeles have each contributed $10,000 to our outreach efforts this year. The leaders of these forward-thinking organizations are stepping forward to support open scholarship in the social sciences.
SocArXiv is a partner of the nonprofit Center for Open Science (COS) and is housed at the University of Maryland, under the administrative direction of sociology professor Philip Cohen, who leads a steering committee of sociologists and academic librarians.
