Heather Morrison, Dramatic Growth June 2006, Imaginary Journal of Poetic Economics, June 30, 2006. There's a lot of good data of which I can only excerpt a small amount:
Growth [in the second quarter of 2006] continued very strong in both the gold and green roads. DOAJ, today at 2,292 journals, added 134 journal titles, an increase of about 1 and 1/2 titles per day (calendar days, not business days), about an equivalent of a 25% annual increase. More than half a million items were added to an OAIster search, for a total of more than 7.6 million items, or about the equivalent of a 24% annual increase. At the current rate of growth, an OAIster search can be anticipated to encompass more than a billion items before the end of 2007....

Note that the DOAJ list does not represent all open access journals, only the ones that have met DOAJ standards, and have gone through the DOAJ vetting process. Jan Szczepanski's list is much longer: over 4,705 titles total as of early December 2005.

The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
I recommend the OA tracking project (OATP) as the best way to stay on top of new OA developments. You can read the OATP feed on a blog-like web page or subscribe to it by RSS, email, or Twitter. You can also help build the feed by tagging new developments you encounter.
