I just released the March 31, 2010 Dramatic Growth of Open Access. Highlights:DOAJ is now at 4,863 journals, having added a net total of 864 journals in the past year for a DOAJ growth rate of over 2 titles per day. The Bielefeld Academic Search Engine now searches over 23 million documents; this is an increase of over 1.2 million in the last quarter, or over 13,000 documents per day. There are now more than 200 open access mandate policies listed in ROARMAP, with strong growth in every category. Compliance with the U.S. National Institutes of Health Public Access Policy is 62% - still not 100%, but definitely getting closer. In the past year,120 more journals began contributing all content as open access to PubMedCentral. There are now more than 5,000 journals around the world using Open Journal Systems (OJS).
