This dataset contains the number and proportion of open access articles with Creative Commons license (CC) by license variant and year for hybrid journals included in the cOAlition S Journal Checker Tool.
Details
Publication period is 2017 - 2022.
Journal's article volume was calculated using Crossref metadata snapshot. Note that only articles published in regular issues aside from supplements containing conference contributions like meeting abstracts, indicated by non-numeric pagination, were included. Also, non-scholarly journal content, such as the table of contents were excluded. In doing so, we followed Unpaywall's paratext recognition approach, which we expanded to include patterns indicating corrections.
CC licenses were also identified through Crossref. License information for author accepted manuscripts ("aam") were not considered.
