Ulrichs' current correct estimate of the total number of active peer-reviewed academic/scholarly journals is 28,094.
So the ball-park figure of 25K we've been using for years was not far from the truth. Many thanks to Sally Morris and Serials Solutions. I got a very slightly different figure -- 28,135 -- using the Ulrichs access from McGill University, but re-doing the sub-totals and percentages as indicated by Serials Solutions, I got: Of these 28,135 active peer reviewed journals TOTAL PEER-REVIEWED: 28,135 ISI-INDEXED: 9,268 (33%) of the 28,135 are indexed in Thomson-Reuters-ISI's Journal Citation reports GOLD OA: 4,365 (13%) of the 28,135 are open access journals (freely available online) (Gold OA, presumably not including Hybrid Gold) (DOAJ lists 8005 journals, but many may be either peer reviewed or "exercise editorial quality control") ISI-INDEXED GOLD OA: 741 (8%) of the 9,268 Thomson-Reuters-ISI-indexed journals are Gold OA journals ENDORSE GREEN OA: By way of comparison, 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. That means 60% of all journal articles can be made Green OA immediately (no embargo) if all institutions mandate it. I did come up with one anomaly, however. De-duping along the lines recommended by Serials Solutions, the result was: AVAILABLE ONLINE: only 3,659 (14%) of the 28,135 are available online (that strikes me as suspiciously low) Stevan Harnad On 2012-08-04, at 2:45 PM, Sally Morris wrote: > Here's a response from Serials Solutions which should clarify the matter once > and for all > > Sally > > > Sally Morris > South House, The Street, Clapham, Worthing, West Sussex, UK BN13 3UU > Tel: +44 (0)1903 871286 > Email: sa...@morris-assocs.demon.co.uk > > > From: Diven, Yvette [mailto:yvette.di...@serialssolutions.com] > Sent: 03 August 2012 22:01 > To: Sally Morris > Subject: RE: [GOAL] Update on Ulrichs estimate of total number of active > peer-reviewed journals: 55, 311 > > From Serials Solutions… > > Dear Colleagues, > > As of 3 August 2012, the number of active peer-reviewed journals listed in > Ulrichsweb is 28,094 titles.
