Author-Level Metrics

Introduction

What are author-level metrics? Why track at this level?

Author-level metrics measure the impact of the scholarly output of a single researcher. Author-level metrics are designed to help researchers assess the cumulative impact of their work, rather than the impact of a single publication. All author-level metrics are derived from article-level metrics: they aggregate or summarize the impact of an author's publications.


Frequently-Used Metrics

  • h-index

Notes and Limitations

As a "general rule of thumb:

  • If an academic shows good citation metrics, it is very likely that he or she has made a significant impact on the field.

"However, the reverse is not necessarily true. If an academic shows weak citation metrics, this may be caused by a lack of impact on the field, but also by one or more of the following:

  • Working in a small field (therefore generating fewer citations in total);
  • Publishing in a language other than English (LOTE - effectively also restricting the citation field);
  • Publishing mainly (in) books."
  • Publishing in a new area
  • Publishing in a subject area that is jurisdictional, e.g. Law
