Why do you need one author to write a scientific paper in philosophy and up to 5,154 for one physics? How far better must philosophers be in typewriting if they manage to the job of over 5,000 physicists? As of 1 June 2017 we start this blog by looking at the use of authorship in scholarly publishing. How is authorship spelled in different scientific disciplines? How did evolve in the last years? What do you, as a scientist, need to contribute to a scientific project, to call yourself an author of a respective publication? We analysed a bibliographic data base with more than with more than 22000 peer-reviewed journals and in 27 subject areas to answer these questions. Now we want to share our results.
