Just released - the June 30, 2012 Dramatic Growth of Open Access
http://poeticeconomics.blogspot.ca/2012/07/inevitability-of-open-access-june-30.html

Highlights:

The most comprehensive search engine for open access archives, The
Bielefeld Academic Search Engine (BASE), now searches more than 36
million documents. There are technical reasons why it is difficult to
deduce the exact number of open access articles. However, some of the
numbers from individual repositories suggest that a number approaching
the BASE total are possible: PubMed connects with over 3.5 million
documents; arXiv, 750,000; Social Sciences Research Network 350,000;
and RePEC, over a million – that’s over 5.5 million documents from
these 4 archives alone – and there are more than 2,000 open access
archives around the world! DOAJ now has just under 8,000 titles, and
is adding at a rate of 3 per day, and the newly launched Directory of
Open Access Books already lists more than a thousand titles from 27
contributing publishers.  The Electronic Journals Library lists over
35,000 journals of interest to academics that are freely available,
and is adding 15 titles per day. The Internet Archive provides access
to 670,000 movies, 100,000 concerts, 1.3 million audio recordings, and
3.5 million texts. No wonder that even open access opponents are now
agreeing that OA is inevitable, and detailed by Stuart Shieber!
