2011 - 2021 OA APCs

This piece provides documentation on the dataset DOAJ 2021 plus, developed for the article Open access journals & article processing charges 2011 – 2021. This is a rich metadata set, with a primary focus on article processing charges (APC) data that also includes a great deal of other data that could be useful for other researchers interested in studying trends in open access journals. The base data is a DOAJ metadata set downloaded on Jan. 5, 2021, with light clean-up to ensure data is in the correct columns, standardize publisher names to the extent it was possible to do so, and remove most URLs that would be primarily useful to DOAJ staff in the process of verifying journals for inclusion. Explanation of column headings, codes and data from other sources included is provided below as well as links to the data documentation of each of these sources. This work is part of the Sustaining the Knowledge Commons (SKC) project funded through a SSHRC Insight Development Grant (2014 – 2016) and Insight Grant (2016 – 2021).
