Analysing hybrid Elsevier articles for correct access rights – Datasets on fee-based Open Access Publishing

"Having read Ross Mounce’s interesting article on wrongly paywalled Open Access articles in hybrid Elsevier journals, I came up with the idea of throwing a bit more data at the issue. We have a lot of those articles in our OpenAPC data collection (2630 articles in 670 different journals, to be precise), and since the contributing institutions reported their APC costs for all of them, we can be pretty confident that they were all paid for and none should be paywalled at the moment."
