This is not Ulrichs for journals, itès Ulrichs for peer-reviewed journals.

DOAJ's 8000 sounds pretty close to Ulrich's 7000. Maybe DOAJ is updating
faster. 16,000 sounds too big and probably includes non-peer-reviewed
journals. But even 16,000 is an order of magnitude lower than 55,000.

Moreover, my purpose in posting the figure was not to focus especially
on the proportion of Gold OA journals, but the number of journals.

And the 60% of journals that have endorsed Green OA eclipses all the
estimates of Gold.
