At a poster session at the Open Repositories Conference 2009, Peter Millington (Technical Development Officer st Sherpa) presented data on the number of publishers/journals used by Wellcome-funded authors that offered a Wellcome-compliant OA publishing policy. Taking a cohort of 3766 papers published in 901 different journals, Millington shows that potential compliance increased from 70% in 2006 to 87% in 2009.
