In a series of short analyses we took a closer look on the practice of (co-)authorship in various disciplines, using a Scopus database (see www.elephantinthelab.org). We found significant differences among the subject areas that we analyzed. While in nearly all disciplines the mere number of authors per article increased (2010-2016), the average number of authors per paper in these disciplines varies considerably. If we just look at the amplitudes of our analyses, the mean of authors spans between 2.1 and 1.268 (Schmidt et al. 2017).
