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
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
9,268 (33%) of the 28,135 are indexed in Thomson-Reuters-ISI's
Journal Citation reports
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
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:
only 3,659 (14%) of the 28,135 are available online
(that strikes me as suspiciously low)

From Serials Solutions…
As of 3 August 2012, the number of active peer-reviewed journals
listed in Ulrichsweb is 28,094 titles. This figure represents a count
of all Primary editions (most of which are print editions, but some
are also electronic) of those titles.
The figure of 55,311 active peer-reviewed journals reflects the count
of the number of all related format editions of the 28,094 active
peer-reviewed journals. (For example, one of the 28,094 active
peer-reviewed journals may have a primary print edition, an online
edition, and also a CD-ROM edition for a total of 3 format editions.)
Dr. Harnad’s search results reflect the current count across all
journal format editions. It is possible to isolate (remove) the
related editions from those search results by applying the Edition
Type filter from the Search Results screen and selecting that filter’s
We hope that this information is helpful.
