Bibliometrics deal with the measurable aspects of scientific publications. Bibliometric analyses and tools can provide support for a wide range of questions, such as:

  • Which journal can I submit my paper to and what about the reputation of this journal?
  • What about the visibility of my research, how can I increase it?
  • Who else is doing research in my field, where can I find cooperation partners?

Author Indicators

Author indicators make quantitative statements about the impact of authors on the basis of citation frequencies. The indicators can be calculated on the basis of various data sources (e.g. Web of Science, Scopus, Google Scholar). Which indicator is suitable depends to a large extent on the discipline and question.

Hirsch-Index, h-index

The h-index represents the number X of publications by a scholar or scientist that have been cited at least X times ( Detailsabout the calculation). The often cited disadvantage of the h-index is that it favours established scientists with a long publication history over young researchers..

Databases with bibliometric data (selection)
