One in five research papers published in 2008 is now freely available on the Internet, according to a recent survey that is itself free to view (B.-C. Bjoerk et al. PLoS ONE 5, e11273; 2010).rnBo-Christer Bjork and his colleagues at the Hanken School of Economics in Helsinki manually checked the availability of 1,837 articles randomly sampled from 1.2 million in Elsevier's Scopus database. Of those, 8.5% were free to view on publishers' websites - known as the 'gold' open access (OA) route. Two-thirds of these were in full open-access journals; the rest were in subscription journals, available either because authors had paid to make their article free or because the journal opted to open up anrnarticle's full content after a delay.
