I am just back from the Berlin 9 conference. The “Berlin” series of conference are named after the Berlin Declaration on Open Access, and this was the first time the annual conference has been held in North America. It’s very hard to summarise my reactions from the conference, there were so many stories showing how opening up scholarship can lead to real benefits, in health, development, innovation and our quality of life. For example, Cyril Muller from the World Bank described how that organisation has adopted an open approach to the work it funds, and to its own operations, and is encouraging the governments with whom it works to do the same. Laura Czerniewicz from the University of Cape Town showed how open education resource, configured for SIM-enabled mobile devices, can make a real difference to some quite seriously disadvantaged students. And Elliot Maxwell highlighted some wonderfully elegant research studies, showing clearly how, when scientific findings and resources are made open, it leads to a greater diversity, quality and application of knowledge. Of course, there are implications. Michael Crow of Arizona State University argued that all this requires us to re-think the university as a social technology, and Philip Bourne highlighted some of the challenges we have in moving to a research practice that is native to the digital environment, genuinely reproducible, and that rewards researchers who move in that direction. The overwhelming impression, though, was of a scholarly community now adopting more open approaches, and beginning to see tangible benefits from that. Berlin 10 is on the African continent for the first time. I hope it will bring new voices to be heard in this community.
