Journals > Peer-Reviewed Journals > Open-Access Journals < Open Access

[Stevan Harnad]

The exchange, below, about the apparent discrepancy in the estimates
of the current number of open access journals is resolved as follows:

Bowker's Ulrichsweb http://www.ulrichsweb.com/ulrichsweb/ indexes
about 250,000 serials. Of those 250,000 serials about 10% (24,000) are
peer-reviewed journals. Of those 24,000 about 2.5% (600) are indexed by
The Directory of Open Access Journals http://www.doaj.org/ which indexes
only peer-reviewed journals.

Other indices and harvesters such as
http://www.j-gate.informindia.co.in/
and
http://rzblx1.uni-regensburg.de/ezeit/index.phtml?lang=en
may index more free online full-text journals than
http://www.doaj.org/
but the open-access movement is focussed on *peer-reviewed* journals only,
as defined in
http://www.soros.org/openaccess/read.shtml
and only peer-reviewed journals are indexed by
http://www.doaj.org/

And let us also not forget that apart from the 2.5% of yearly
articles from the 24,000 peer-reviewed journals that are openly
accessible because they are published in the 600 open-access ("gold")
journals to date, at least three times as many yearly articles
(7.5%) from the 24,000 peer-reviewed journals are openly
accessible because they are self-archived by their authors:

This current total of 10% open access can immediately be increased
to at least 55% by self-archiving all the articles in the 55%
of peer-reviewed journals that are already "green" (or "blue" or "gold"):
