270 SpringerOpen journals were studied. 33 (12%) have ceased publication, 15 have been transferred to another publisher, and 7 are now hybrid. Of the 215 active journals published by SpringerOpen, 54% charge APCs. The average APC was 1,212 EUR, an increase of 8% over the 2018 average, 6 times the EU inflation rate for June 2019 of 1.3%. 58% of the 96 journals for which we have 2018 and 2018 data did not change in price; 5% decreased in price; and 36% increased in price. Price increases for journals that increased in price ranged from 3% to 109% (double the inflation rate to double in price). Journals with the highest volume of publishing were the most likely to have increased in price. This will amplify the effective percentage of articles with price increases for APC payers. 40% of the journals are sponsored by a university, society, government, or other not-for-profit partner, and have no publication fee. The sustainability of these sponsorships is not clear. 12 journals appear to have recently switched from “no APC” to “now APC”, with APCs only slightly below the SpringerOpen average. The affordability of the SpringerOpen partnership approach is called into question. SpringerOpen’s average APC does not compare favorably either to average academic salaries in a low to middle income country (with Egypt as an example) or to OJS Premium journal hosting services (the break-even point is 2 articles per year, i.e. a journal that publishes 3 articles per year saves money with OJS Premium as compared to SpringerOpen). Even a sponsor based in Germany only pays half the APC, raising a question about whether SpringerOpen sponsorships are sustainable anywhere.
