Gray OA 2014-2017: A Partial Followup, the October 2017 Cites & Insights (17.9), is now available for downloading at https://citesandinsights.info/civ17i9.pdf
The single-essay issue is 42 pages long (38 numbered pages).
It updates article-count and status-code information (but not APC/fee information) for gray OA journals not in DOAJ, adding full-year 2016 article counts and January-June 2017 counts, doubled for ease of comparisons. Journals in Gray OA 2012-2016 that have been added to DOAJ have been removed from the new report.
