"While some librarians are for- and some librarians are against- open access, I sit in the former camp. I am not going to preach about the benefits of OA, which are well documented, I’m just going to state that for me and others, including governments, the debate on OA is over. It is an inevitable progression of scholarly communication in the digital information age. Furthermore, it is an important evolution of science & knowledge. How we implement OA via Gold or Green is however worthy of discussion. It will be interesting to see how the UK fairs out in this regard, especially when most other English speaking countries and areas are going the Green route (USA, Ireland, Australia, EU).When advocating for OA I find it is useful to start with policy and it’s important to keep up to date with this area as it is evolving. For a good global overview on OA policies please see this Canadian overview and this Australian overview. The next challenge is infrastructure and the EU has been stepping up progress in this regard, by providing a dedicated site with resources for Repository Managers, Researchers & Project Co-Coordinators on OpenAire. In some EU countries (Denmark, Bulgaria, Croatia, Finland, Germany, Hungary, Iceland, Ireland, Italy, Lithuania, Netherlands, Norway, Romania, Slovakia, Spain, Sweden, Turkey, UK) national open access groups have formed to look at policy and its implementation particularly with regard to Horizon 2020 funded projects across European countries."
