Harnad, S. (2011) What Is To Be Done About Public Access to
Peer-Reviewed Scholarly Publications Resulting From Federally Funded Research? (Response to US OSTP RFI). Technical Report , Electronics and Computer Science, University of Southampton. (Submitted to OSTP) http://eprints.ecs.soton.ac.uk/23080/
Steven Harnad outlines why the minimum should be to mandate that:
(i) the fundee’s revised, accepted refereed final draft
(ii) of all refereed journal articles (including refereed conference articles) resulting from the funded research must be
(iii) deposited immediately upon acceptance for publication
(iv) in the fundee’s institutional repository.
(v) Access to the deposit must be made gratis OA (online access free for all) immediately (no OA embargo) wherever possible (over 60 % of journals already endorse immediate gratis OA self-archiving).
