Open Access in the UK - graph from Nature illustrating difference in open access by discipline. Found that of the approx. 85,000 articles published by researchers in the U.K. indexed in Web of Science in 2010, 40% were open access as of 2012 - 5% gold, 35% green. (My note - Web of Science will tend to understate research activity in the humanities and social sciences). Data from Yassine Gargouri according to Alma Swan on the GOAL list.

  • The growth of the PLoS ONE exceeded even the most optimistic predictions. In the first full year of publication it published 1,230 articles (making it larger in volume than all but about 100 journals) and, within 4 years, it became the largest peer-reviewed journal in the world. To date, PLoS ONE has published more than 28,700 articles and in 2011 alone it will publish almost 14,000 articles (meaning that approximately 1 in 60 of all articles indexed by PubMed for 2011 will have been published in PLoS ONE).

Excerpt:
2010 is our 16th year and it is off to a great start. Our eLibrary (http://ssrn.com/search) has delivered over 37.4 million downloads to date and grown to 290,000 documents and 138,000 authors - increases over the last year of 53,000 and 22,000 respectively. Our CiteReader technology, developed with ITX Corp, has captured over 6 million references, 5.7 million footnotes, and close to 3.9 million citation links. We believe this growth in multi-disciplinary, open access content is exciting and contributing to innovative scholarly research in social science and humanities.

PLoS One: Open Access to the Scholarly Journal Literature: Status 2009. Random study of 1,837 titles found of articles published in 2008, over 8% were open access on the publisher's website, and over 11% otherwise freely available, for an overall average of over 20% of articles freely available. There was a disparity in results by discipline.

Strong Open Access Growth Reported by Hindawi. Hindawi's figures for 2009 show more than doubling of submissions, and strong growth in accepted manuscripts, indicating that in addition to strong growth in number of OA journals, there is evidence of strong growth in articles within established OA journals as well.
