In “Web of Science, Scopus, and Open Access: What they are doing right
and what they are doing wrong”

Ryan Regier discusses the current capacities and limitations of
WoS,SCOPUS, Google Scholar in finding OA papers and their proportions
(OA/total). Most of the discussion is about Gold OA, but Regier notes
that GS can be used for Green OA, though inefficient.

I would add that the way to find just about all OA articles and to
calculate the proportion of a university’s total articles that are OA
is not to (1) seek them or (2) their proportion in WoS or SCOPUS. That
way, the only OA articles you’ll find are the Gold OA ones, and their
proportion.

Yes, google scholar (GS) is the way an individual researcher can find
OA articles on a particular topic, and yes the search, as well as the
calculation of the proportion has to be done by hand (to see which
hits have an OA version). This is much more useful than WoS or SCOPUS,
because it covers Green OA too, but it requires a lot of manual work
that could be reduced as soon as GS does a little tweaking of data and
metadata it already has (author name, institution, pub date), even to
an approximation.

Already (to a very crude approximation) I can get all the GS articles
on “slender loris” (3200) narrow it down to 2014-2015 (198) or to
(“slender loris” “university of illinois”) (42) or to (“slender loris”
“university of illinois”) 2014-2015 (2).

Combining WoS or SCOPUS data and GS I could also get an approximate
estimate of OA/total output, for an individual university, per year,
without reaching the GS robot limit for an institution.

Tedious. inefficient, and very approximate, admittedly, but a taste of
what’s to come (and what GS can and will make much easier and more
efficient) — once universities and funders do their part, which is to
adopt strong, effective Green OA mandates.
