The 12th conference in the Berlin Open Access series (Berlin, 8-9 December, 2015) will be an invitation-only workshop for high-level representatives of the world’s most eminent research organizations. Some 100 delegates will convene in Berlin to discuss how the goal of Open Access can be realized more rapidly. The central theme will be the transformation of subscription journals to Open Access, as outlined in a recent white paper by the Max Planck Digital Library (http://dx.doi.org/10.17617/1.3). On the first day, there will be a review of the level of consensus about the extent to which this transformation is our shared goal; the second day will concentrate on how this goal can actually be achieved in the coming years. Delegates should be prepared to engage actively in these discussions by articulating the views of their constituencies.
