2010 – 2019 APC update | Sustaining the Knowledge Commons / Soutenir les savoirs communs
This is an update of the 2010 study of Solomon & Björk (2012) of a sample of 1,046 journals charging APCs listed in DOAJ at that time. 74% of these journals are still active and actively charging publication fees. The average APC reported by Solomon & Björk was 906 USD; the average in 2019 for the 739 journals for which we have APC data for both years is 1,363 USD. This represents a 50% price increase during this time frame, an increase that is 3 times the inflation rate. Not all journals increased in price; some decreased or remained the same price. Nearly a quarter of the journals (23%) are ceased or not found. Most of this attrition rate can be attributed to new OA APC-based commercial publishers with a start-up strategy involving roll-out of a broad range of journals, with unsuccessful journals being retired.
