Change and growth in open access journal publishing and charging trends 2011–2021.

Two methods are employed, a modified replica and a status update of the 2011 journals. Data is drawn from multiple sources and datasets are available as open data (Morrison et al, 2021). Most journals do not charge APCs; this has not changed. The global average per-journal APC increased slightly, from 906 USD to 958 USD, while the per-article average increased from 904 USD to 1,626 USD, indicating that authors choose to publish in more expensive journals. Publisher size, type, impact metrics and subject affect charging tendencies, average APC, and pricing trends. Half the journals from the 2011 sample are no longer listed in DOAJ in 2021, due to ceased publication or publisher de-listing. Conclusions include a caution about the potential of the APC model to increase costs beyond inflation. The university sector may be the most promising approach to economically sustainable no-fee OA journals. Universities publish many OA journals, nearly half of OA articles, tend not to charge APCs and when APCs are charged, the prices are very low on average.enopen accessarticle publishing chargesAPCscholarly publishingArticlehttps://doi.org/10.1002/asi.24717
