Retrospective and prospective study of the evolution of APC costs and electronic subscriptions for French institutions

A journal article dataset has been developed with metadata of articles by France-based authors in the period 2013-2020. The purpose of this dataset was to form a basis for the retrospective and prospective analyses of the total costs of APCs paid by French institutions. This article presents the main results of the retrospective analysis of the dataset regarding the numbers of APC-paid articles with a France-based corresponding author.
