I find this figure very surprising. What appears to be the same search, carried out this past March, came up with a (to me) much more credible figure of 27,566.

_____ From: goal-boun...@eprints.org [mailto:goal-boun...@eprints.org] On Behalf Of Stevan Harnad Sent: 03 August 2012 20:08 To: Global Open Access List (Successor of AmSci) Cc: LibLicense-L Discussion Forum Subject: [GOAL] Update on Ulrichs estimate of total number of active peer-reviewed journals: 55, 311 For years now, I've just been re-using an old Ulrich <http://ulrichsweb.serialssolutions.com> 's estimate of about 25,000 for the total number of active peer-reviewed journals. Prompted by a recent query from someone, I've checked again, and -- unless I've made a mistake in my search -- the number now seems to have doubled to 55,311. The parameters I used to get this figure were (1) Active, (2) Journal, (3) Academic/Scholarly, (4) Refereed/Peer-reviewed, A further breakdown shows that of these 55,311 active peer reviewed journals, 23,527 (43%) are available online 9,354 (17%) are indexed in Thomson-Reuters-ISI's Journal Citation reports 6,962 (13%) are open access journals (freely available online) (Gold OA, presumably not including Hybrid Gold). 769 (11%) of the 9,354 Thomson-Reuters-ISI-indexed journals are open access journals -- According to the last estimate of journals indexed by SHERPA/ROMEO (which does not include all the journals indexed by Ulrichs, but does include most of the top journals indexed by Thomson-Reuters-ISI): 60% of journals recognize the author's right to provide immediate, un-embargoed open access upon self-archiving their final drafts in their institutional repositories. -- It would be helpful if others could check and confirm these figures.
