This report touts the public cost savings of Open Access research dissemination policy in the UK.

The total cost to the public sector of accessing journal papers is around £135 million per annum. The savings that accrue from the availability of Open Access articles (using both Green and Gold routes) amount to £28.6 million (£26 million in access fees and £2.6 million in time savings).

Hooray, that means more money for the British government to reinvest in the health care and other social services it's so committed to ... oh, wait.

Anyway, the complete report is available here.

(Also: for what the Green and Gold references mean - they're publisher rankings in terms of how open their access is. See the Sherpa/RoMEO database for more.)
