From: Stevan Harnad <[log in to unmask]> Date: Sun, 29 Nov 2015 08:21:18 -0500 In “Web of Science, Scopus, and Open Access: What they are doing right and what they are doing wrong” https://awayofhappening.wordpress.com/2015/11/27/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.
