From: Stevan Harnad <[log in to unmask]> Date: Thu, 2 Oct 2014 08:16:30 -0400 Requirements for eligibility for REF2020 (papers must be deposited immediately upon acceptance for publication -- access to deposit must be made open immediately or, at the latest, by the end of the permissible embargo). If your institution has adopted (or upgraded) and OA policy, please register it in ROARMAP to inspire other institutions to adopt and register their OA policies. ROARMAP is also conducting studies, with the help of the data from the new ROAR database (coming soon) to monitor and record the effectiveness of OA policies in terms of their deposit rate (percentage of annual published output that is deposited) and deposit latency (when the papers are deposited, relative to publication date). OA Policies differ in their requirements. It is hoped that the comparative data will help institutions that already have an OA policy to monitor and compare its effectiveness with other policy models and will help institutions planning to adopt and OA policy to pick the most effective model.
