The data are from Yassine Gargouri (who has used the methodology he previously used, which consists of trawling the web for openly accessible full-texts and comparing the number of those with the papers in Web of Science, which is not a perfect, but a reasonable measure of the ‘universe’ for UK researchers).<br>
