The Dramatic Growth of Open Access version showing annual growth over the past year has been corrected (the earlier version showed numeric growth as a percentage of the current year rather than the previous year).
This means that all annual growth percentages are actually higher than originally reported. For example, both RePEC and E-LIS showed growth of more than 30% in the past year, not 25% as previously reported.
The corrected version has been posted at http://spreadsheets.google.com/pub?key=pqCs8wrw32HH5igWgsHZ6SQ, and at the Dataverse Network.
