Thanks ever so much, Kat. Those data are terrific!

Is there any possibility that you could make that analysis into
a regular feature of the OAIster homepage, either as a periodic static
snapshot or, better still, a dynamically updated one of:
http://www.ecs.soton.ac.uk/~harnad/Temp/self-archiving_files/Slide0023.gif

A comparable dynamic analyzer for the Directory of Open Access Journals DOAJ
homepage http://www.doaj.org/ would be extremely useful and informative
too, as well as such an analyzer for the new SHERPA/ROMEO tally of
"green" journals (number of journals officially endorsing self-archiving).
http://www.lboro.ac.uk/departments/ls/disresearch/romeo/Romeo%20Publisher%20Policies.htm

These 3 highly related sets of data should be interlinked to one another,
to provide a clear indicator of the ongoing worldwide growth of OA in all
respects (growth in (1) the number of OA archives and self-archived OA
articles in them, (2) growth in the number OA journals and OA articles
in them, and (3) growth in the number of "green" journals, hence the
minimum number of *potentially* OA articles!).

Tim Brody has now created such a visualizer for 126 OAI Archives
http://archives.eprints.org/eprints.php?page=all 
as well as an analyzer of the growth rate for both
archives and papers among (1) 62 exclusively institutional
archives as well as among (2) 93 eprints.org archives only:
http://archives.eprints.org/eprints.php?action=analysis

Something like that for all of OAister, DOAJ and Romeo would be a
tremendous help, an eye-opener for the world research community, and a
great stimulant for OA.
