You might want to try the paperback version of GOAj3: Gold Open Access Journals 2012-2017 or Gold Open Access Journals by Country 2012-2017–or, for that matter, if you’re interested in gray OA, Cites & Insights 17, which includes both iterations of the study.
They’re all on sale now through June 21, 2018, 20% off–as are all Lulu print products, including my other books–if you use the coupon code

Update 6/22: That sale’s expired, but there’s a new three-day sale that’s even better for the GOAJ books:
10% off–and free ground shipping. Through June 25, 2018. Code
