UK PubMed Central Blog: Increasing proportion of UKPMC articles are open access

“A previous post on this blog showed how the proportion of open access content in UKPMC was increasing. By open access, we mean ‘free to read AND free to reuse’, at least for non-commercial purposes, although all the content on UKPMC is free to read. At that time the trend reported showed that the proportion of open access content had grown to 33% in 2009. In 2010, the proportion of articles that are open access has risen to 41% of the articles published that year, or almost 70,000 articles in real numbers.  The graph below shows the growth of open access articles in UKPMC between 2001 and 2010.”
