Fractional Authorship & Publication Productivity

In this first Perspectives paper, Fractional Authorship & Publication Productivity, we look at how patterns of authorship are evolving. With the growth in publications and the length of author lists, we examine what that means for authors – are they writing more each year, or just writing more collaboratively?


  • Authors divide their research output across publications, contributing via research collaborations
  • The trend is for authors to produce more publications per year (increased fractionalization) but for the overall number of publications per author to decrease
  • We suggest that the effort required to participate in research collaborations is a factor in the decrease in publications per author
