During the session, Louise referred to HEFCE’s future requirements for making research open access so that it would count towards the post-2014 REF. Is it necessary to upload research conducted in previous employment at other institutions? The policy will apply from 1 April 2016 to accepted journal articles/conference proceedings with ISSN so Lancaster researchers would have to deposit and make it Open Access from that point to count towards the post-2014 REF. They wouldn’t have to make research open access retrospectively.
