Spatial bibliometrics on the city level

Abstract

It is very popular in bibliometrics to present results on institutions not only as tabular lists, but also on maps (see, for example, the Leiden Ranking). However, the problem with these visualisations is that institutions are frequently spatially clustered in larger cities whereby institutions are positioned one above the other. In this Brief Communication, we propose as an alternative to visualise bibliometric data on the city rather than the institution level to avoid this problem.
