A presentation by Robert Kiley (Wellcome Trust) given at the annual conference of the Association of Subscription Agents and Intermediaries that looks at the Wellcome Trust experience with the author-pays, open access model. Looking at Wellcome-funded papers published in the quarter of 2010, Kiley calculates that the average cost of papers published under the author-pays model — either through a hybrid or full open access option – was $2,367.
