That is certainly good news (and perhaps less surprising, considering that
Physics is the most advanced in Open Access)!
How many refereed Physics journals are there worldwide? That would make
it possible to know the proportion of the total that is open-access so
far.
The excellent (truly remarkable!) Regensburg resource Ebs cites below:
http://rzblx1.uni-regensburg.de/ezeit/index.phtml?bibid=AAAAA&colors=7&lang=en
lists 759 Physics journals, of which 103 (14%) are open access. (Is this
complete?)
A 3-year series of the corresponding data would also give us a
chance of extrapolating the trend, to estimate when it will approach 100%
open-access at the present rate.
Another useful set of data would be the corresponding figures for
self-archived papers in Physics. We need to know how many refereed
papers appear annually in Physics, and then what proportion of them are
made openly accessible by their authors through self-archiving. Again,
a 3-year series would allow us to extrapolate.
ArXiv's 11-year data provide part of the answer:
http://arxiv.org/show_monthly_submissions
but they of course need to be supplemented by (1) estimates of the total
annual Physics refereed publication count as well as (2) the Physics
self-archiving figures for archives other than ArXiv (but not counting
the archives of the open-access journals, of course).
A 3-year series of those data (total vs. open-access subset, for the
open-access journal corpus and for the author/institution self-archived
corpos) would give a good picture of where things stand, and how fast
they are going, in Physics.
Even better would be a series of such estimates in all the other
disciplines too, as well as for the entire peer-reviewed corpus, across
all disciplines.
And (subtle, but critically important!), we need to know the *quality
level* of the current open-access journals -- as well as of the current
self-archived refereed articles -- within the hierarchy of journals
(and articles). An estimate of this would come from the journal impact
factors (and perhaps also the rejection rates) of the open-access journals
(as estimated, for example, by ISI's
http://wos.mimas.ac.uk/),
compared to the rest, and from the author and article citation (and
perhaps usage) impacts for the self-archived article (as estimated, for
example, by
http://citebase.eprints.org/ and
http://citeseer.nj.nec.com/cs)
Here is a prediction: With a few prominent exceptions, most of the
current open-access journals will come from the lower range of the journal
hierarchy. These are the small journals with small readerships, low
visibility and low impact, struggling to make ends meet. These journals are
of course very welcome among the ranks of the open-access journals,
but they are, in a sense, not the primary targets: the journals toward
the top of the hierarchy.
So the 3 year time-series data for the growth of open access journals
will be very useful and informative, but we will also have to see where
in the journal hierarchy the growth is occurring. The bottom is, of
course, the easier part to convince of the benefits of open access!
Here is another prediction: In the corresponding three-year time-series
data for the growth of open access through author self-archiving, there
will *not* be the (negative) correlation with journal-quality that
(I predict) there will be in the case of open-access journals, because
individual researchers will be self-archiving on their own initiative
rather than on the basis of the hierarchical level of the journal in
which their articles appear.
For self-archiving, Oaister
http://oaister.umdl.umich.edu/o/oaister/viewcolls.html
with its 1,042,164 records from 119 institutions might be one of the
sources of the data for comparing the progress of open access through
self-archiving of toll-access articles (BOAI-1) with open access through
open-access journals (BOAI-2).
(It is one of the important features of the BOAI-2 strategy, as
practised by PLoS, that they are targetting the very top of the
quality-hierarchy. For whereas the bottom-up BOAI-2 path to open access
may be a long one -- with the weaker journals spontaneously converting
only out of necessity -- PLoS's top-down strategy may prove much faster.)

That is certainly very encouraging! But to know what it means (especially
for the rate of progress towards universal open access to the entire
peer-reviewed literature), we will need the finer-grained time-series
analyses and comparisons I outlined above, including the hierarchical
level data. I hope someone will do those analyes! The rich data are there,
to be mined (and there are refereed articles to be written on the
findings!).
