What publishers can take away from the latest early career researcher research ($), a five-page “Industry Update” for the journal Learned Publishing, 28th April 2018…

“ResearchGate is unquestionably the scholarly elephant in the room, which despite being just 10 years old boasts 15 million research members and is still growing at a rate of knots. … publisher offerings can look monastic and parochial by comparison. […] It looks rather like the new scholarly world order.” […] “Much depends on whether ECRs [early-career-researchers] take their millennial beliefs in sharing, openness, and transparency into leadership positions. [and if] publishers [start] feeding ResearchGate rather than competing with it – [making it] a publishing Amazon”.

The Update is by the team doing an industry-supported three-year cohort study of search and similar practices. Their first two reports are Early Career Researchers: the harbingers of change? Year One 2016 and now also the Year Two 2017 report, both free and public at the same website. Apparently the cohort of around 100+ is all science and social studies.

Also fairly new, and related, “ResearchGate and Academia.edu as networked socio-technical systems for scholarly communication: a literature review” (OA), in the Research in Learning Technology journal, 20th February 2018…

“a thorough understanding is still lacking of how these sites operate as networked socio-technical systems reshaping scholarly practices and academic identity. This article analyses 39 empirical studies published in peer-reviewed journals with a specific focus on ResearchGate and Academia.edu.”

Google Search currently suggests circa 72-million full-text PDFs at ResearchGate, although given the above Industry Update statement on ‘the 15m members’ we can probably assume some 10m of those PDFs are just CVs (which are nearly all excluded from JURN, by the way). Remove other fluff and I guess there might be circa 50m proper papers there. It would then be interesting to work out what “the uniques” are, by removing the papers freely available elsewhere in repositories and OA journals and suchlike. I’d very roughly guess that including ResearchGate PDFs in JURN may bring in some 5m to 8m papers not found elsewhere.
